### A opaque is a dark shape caused when an object blocks light

• A.

True

• B.

False

B. False
Explanation
An opaque is not a dark shape caused when an object blocks light. In fact, an opaque is the opposite of transparent, meaning it does not allow light to pass through. It is a term used to describe materials or objects that do not transmit light and are therefore not see-through.

Rate this question:

• 4.

### Objects that can make their own light are_________

• A.

Luminous

• B.

Transparent

• C.

Opaque

• D.

Translucent

A. Luminous
Explanation
Luminous objects are those that can emit their own light. They have the ability to produce and emit light energy. This is in contrast to transparent, opaque, and translucent objects, which do not emit light on their own. Transparent objects allow light to pass through them without scattering, opaque objects do not allow any light to pass through them, and translucent objects allow some light to pass through but scatter it in different directions.

Rate this question:

• 5.

### What is related to light?

heat
Explanation
Heat is related to light because light is a form of energy that can generate heat. When light is absorbed by an object, it can increase the kinetic energy of its molecules, leading to an increase in temperature. This is why we can feel warmth when exposed to sunlight or when standing near a light source. Additionally, light can also be converted into heat through processes like absorption or reflection, further emphasizing the relationship between the two.

• 6.

### Light and _________ are related to each other

• A.

Electricity

• B.

Heat

• C.

Rays

• D.

B. Heat
Explanation
Light and heat are related to each other because light is a form of electromagnetic radiation that carries energy. When light is absorbed by an object, it can be converted into heat energy, causing the object to increase in temperature. This is why we feel warmth when exposed to sunlight or when using a light bulb. Therefore, heat is the correct answer as it represents the relationship between light and the thermal energy it can generate.

• 7.

### Objects that cannot make their own light are____________

• A.

Luminous

• B.

Nonluminous

• C.

Transparent

• D.

Opaque

B. Nonluminous
Explanation
Nonluminous objects are those that do not produce their own light. They rely on external sources of light to be visible. Luminous objects, on the other hand, are able to emit their own light. Transparent and opaque are not relevant to the question as they refer to the ability of an object to allow light to pass through or not.

Rate this question:

• 8.

### A __________ is a dark shape cause when an object blocks light

• A.

Opaque

• B.

• C.

Ray

• D.

Window

Explanation
A shadow is a dark shape caused when an object blocks light. When light encounters an object, it cannot pass through it, resulting in the formation of a shadow on the opposite side of the object. Shadows are created when light is obstructed by an opaque object, preventing the light from reaching a surface and creating a dark area behind it. Therefore, the correct answer is shadow.

Rate this question:

• 9.

### Why does an opaque object cause a shadow?

• A.

Transparent objects block the light causing a shadow

• B.

Translucent objects block the light causing a shadow

• C.

Opaque objects block the light causing a shadow

• D.

Because the sun is shining a different way.

C. Opaque objects block the light causing a shadow
Explanation
Opaque objects block the light causing a shadow because they do not allow light to pass through them. Unlike transparent or translucent objects, which allow some or all light to pass through, opaque objects absorb or reflect light, preventing it from reaching the surface behind them. As a result, a shadow is formed on the surface opposite to the direction of the light source, as the light is blocked by the opaque object.

### Lenses are used in eyeglasses, microscopes, magnifying glasses, and telescopes.

• A.

True

• B.

False

A. True
Explanation
Lenses are indeed used in eyeglasses, microscopes, magnifying glasses, and telescopes. These optical devices rely on lenses to bend and focus light, allowing for clearer vision, magnification of small objects, and the observation of distant objects. Therefore, the statement "Lenses are used in eyeglasses, microscopes, magnifying glasses, and telescopes" is true.

### Lenses that bend light outward are used to correct nearsightedness. These lenses are called convex.

• A.

True

• B.

False

B. False
Explanation
Convex lenses actually bend light inward, not outward. They are used to correct farsightedness, not nearsightedness. Nearsightedness is corrected using concave lenses, which diverge the light and help focus it properly on the retina. Therefore, the given statement is false.

### Lenses that bend light inward are used to correct farsightedness. These lenses are convex

• A.

True

• B.

False

A. True
Explanation
Convex lenses are thicker in the middle and thinner at the edges, causing them to bend light inward. This bending of light helps to focus the light rays onto the retina, which is necessary for correcting farsightedness. Therefore, the statement that lenses that bend light inward are used to correct farsightedness and are convex is true.

### The back part of the eye where an image forms is called the ___________

• A.

Cornea

• B.

Optic nerve

• C.

Retina

C. Retina
Explanation
The back part of the eye where an image forms is called the retina. The retina is a layer of tissue that lines the inner surface of the back of the eye. It contains millions of light-sensitive cells called photoreceptors that detect and convert light into electrical signals, which are then transmitted to the brain through the optic nerve for visual processing. The cornea is the transparent front part of the eye that helps to focus light, while the optic nerve is responsible for transmitting visual information from the retina to the brain.

### The _______ is the part of the eye that refracts light to focus it

• A.

Lens

• B.

Pupil

• C.

Cornea

A. Lens
Explanation
The lens is the part of the eye that refracts light to focus it. It is a transparent structure located behind the iris and the pupil. The shape of the lens can be adjusted by the ciliary muscles to change the focal length and allow for clear vision at different distances. When light enters the eye, it passes through the cornea and the lens, which bend the light rays and focus them onto the retina at the back of the eye. This process helps to form a clear and focused image on the retina, which is then transmitted to the brain for interpretation.

Rate this question:

• 21.

### The part of the eye that sends message to the brain is called the________

• A.

Iris

• B.

Optic nerve

• C.

Pupil

B. Optic nerve
Explanation
The optic nerve is the correct answer because it is the part of the eye that carries visual information from the retina to the brain. It is responsible for transmitting electrical impulses generated by the retina to the visual cortex in the brain, where the information is processed and interpreted as visual images. The iris is the colored part of the eye that controls the size of the pupil, while the pupil is the opening that allows light to enter the eye.

Rate this question:

• 22.

### The transparent, curved covering in the front of the eye is called the_________

• A.

Sclera

• B.

Pupil

• C.

Cornea

C. Cornea
Explanation
The transparent, curved covering in the front of the eye is called the cornea. The cornea is a clear, dome-shaped structure that covers the front part of the eye. It plays a crucial role in focusing light onto the retina, which allows us to see clearly. The cornea also helps to protect the eye from dust, germs, and other foreign particles.

Rate this question:

• 23.

### The opening in the iris that allows light to enter the inside of the eye is called_________

• A.

Pupil

• B.

Retina

• C.

Sclera

A. Pupil
Explanation
The opening in the iris that allows light to enter the inside of the eye is called the pupil. The pupil is responsible for regulating the amount of light that enters the eye by changing its size. When there is low light, the pupil dilates to allow more light in, and when there is bright light, the pupil constricts to reduce the amount of light entering the eye. The size of the pupil is controlled by the muscles in the iris.

### White light is made of only one color

• A.

True

• B.

False

B. False
Explanation
White light is not made of only one color. In fact, white light is a combination of all colors of the visible spectrum. When white light passes through a prism, it gets refracted and separates into its constituent colors, creating a spectrum of colors. This phenomenon is known as dispersion. Therefore, the statement that white light is made of only one color is incorrect.

Rate this question:

• 25.

### White light is made up of many colors

• A.

True

• B.

False

A. True
Explanation
White light is made up of many colors because it is a combination of all the colors in the visible spectrum. When white light passes through a prism, it gets separated into its constituent colors, creating a rainbow. This phenomenon is known as dispersion. Each color in the rainbow represents a different wavelength of light, and when combined, they create white light. This can also be observed when white light passes through water droplets in the atmosphere, resulting in the formation of a rainbow. Therefore, the statement "White light is made up of many colors" is true.
