Questions and Answers
- 1.
Out of these four options, which surface can light pass through?
- A.
Opaque
- B.
Transparent
Correct Answer
B. TransparentExplanation
Light can pass through a surface that is transparent. Transparency refers to the property of allowing light to pass through without scattering or diffusing it. Transparent materials such as glass, water, and air allow light to pass through them, making objects on the other side visible. In contrast, opaque surfaces do not allow light to pass through, blocking the transmission of light and making objects behind them invisible.Rate this question:

_______ is not a source of light because the suns light reflects onto it.
Correct Answer
moonExplanation
The moon is not a source of light because it does not produce its own light. Instead, it reflects the light from the sun. This is why we see the moon shining in the night sky. If the moon were a source of light itself, it would emit its own light and not rely on the sun's light for illumination.Rate this question:

Objects that have that have lights of their own are called____________ of light.
Correct Answer
sourcesExplanation
Objects that have their own lights are called sources of light. These objects emit light energy, making them the origin or starting point of light rays. They can include natural sources like the sun, stars, and fire, as well as artificial sources like light bulbs and lamps. These sources emit light in various forms, such as visible light, infrared light, or ultraviolet light.Rate this question:

Out of these four questions, which one is not a source of light?
- A.
Sun
- B.
Moon
Correct Answer
B. MoonExplanation
The moon is not a source of light because it does not produce its own light. Instead, it reflects the light from the sun. The sun, on the other hand, is a source of light as it emits its own light and heat. Therefore, the moon is the correct answer as it does not emit light independently.Rate this question:

When an object is blocking the path of light, it creates a _______.
Correct Answer
shadowExplanation
When an object blocks the path of light, it creates a shadow. Shadows are formed when light is obstructed by an opaque object, preventing it from reaching a surface. The object casts a silhouette on the surface behind it, creating a darker area where light is not able to reach. Shadows are formed due to the absence of light in the blocked area, resulting in a contrast between the illuminated and shaded regions.Rate this question:

How is a shadow formed?
- A.
When an object is blocking the lights path.
- B.
When the light turns to the east.
- C.
When the light turns to thw west
Correct Answer
A. When an object is blocking the lights path.Explanation
A shadow is formed when an object blocks the path of light. When light rays from a source hit an object, they are unable to pass through it, resulting in the formation of a shadow on the opposite side of the object. The shadow is created because the light rays cannot reach the surface behind the object, causing that area to be darker compared to the surrounding areas.Rate this question:
