As you know, light travels in a straight line from its source. What do you know about shadows? Take this quiz on light and shadow to test your knowledge. When light reaches a solid object, the light is prevented from moving through the object. Do you know what the result of this process is? What happens to shadows during sunlight? You will find some more knowledgeable questions here! Do not forget to share the quiz.

• 1.

### When an object blocks the light, what is formed?

• A.

A reflection

• B.

An illumination

• C.

• D.

A refraction

Explanation
When an object blocks the light, a shadow is formed. This occurs because the object prevents the light from reaching a certain area, creating a dark region behind it. Shadows are formed when light is obstructed by an opaque object, causing a lack of illumination in that particular area. Shadows can vary in size and shape depending on the position and size of the object blocking the light source.

Rate this question:

• 2.

### ________ is formed when an opaque object blocks the light rays of any light source.

Explanation

Rate this question:

• 3.

### When an object moves closer to a light source, its shadow

• A.

Gets smaller

• B.

Gets bigger

• C.

Changes shape

• D.

Stays the same size

B. Gets bigger
Explanation
When an object moves closer to a light source, its shadow gets bigger. This is because the closer the object is to the light source, the larger the shadow it casts. As the distance between the object and the light source decreases, the angle at which the light hits the object changes, resulting in a larger shadow being formed.

### When an object moves away from a light source, its shadow

• A.

Changes shape

• B.

Gets bigger

• C.

Stays the same size

• D.

Gets smaller

D. Gets smaller
Explanation
As an object moves away from a light source, its shadow gets smaller. This is because the farther the object is from the light source, the less direct light it receives. As a result, the shadow cast by the object becomes less pronounced and smaller in size. This phenomenon can be observed in everyday life when objects are moved away from a light source, causing their shadows to shrink in size.

### The sun shines on a person, creating a shadow. Mark the statements that are true. (Select all that apply)

• A.

The sun is a source of light.

• B.

The person always has a shadow.

• C.

The person blocks light from the sun.

• D.

The shadow is the same shape as the person.

• E.

Light from the sun passes through the person.

A. The sun is a source of light.
C. The person blocks light from the sun.
D. The shadow is the same shape as the person.
Explanation
The statement "The sun is a source of light" is true because the sun emits light and is the primary source of light on Earth. The statement "The person blocks light from the sun" is true because when the sun shines on a person, the person's body blocks some of the light from reaching the ground, creating a shadow. The statement "The shadow is the same shape as the person" is true because the shadow is formed by the blocking of light by the person's body, resulting in a shadow that has a similar shape to the person.

Rate this question:

• 6.

• A.

Behind you

• B.

Next to you

• C.

At the side of you

• D.

In front of you

D. In front of you
Explanation
When the sun is behind you, your shadow is in front of you. This is because the light from the sun shines in the opposite direction of your shadow. As a result, your shadow is cast in front of you, extending away from your body.

### Why does the shadow made by the sun move over a day?

• A.

Because the weather changes

• B.

Because someone moves the objects

• C.

Because the sun appears to move across the sky

• D.

Because it's magic

C. Because the sun appears to move across the sky
Explanation
The shadow made by the sun moves over a day because the sun appears to move across the sky. As the Earth rotates on its axis, it creates the illusion that the sun is moving from east to west. This apparent movement of the sun causes the angle of the sunlight to change throughout the day, resulting in the movement of the shadow.

Rate this question:

• 8.

• A.

In the morning, when the sun is rising

• B.

At midday, when the sun is directly overhead

• C.

In the evening, when the sun is setting

• D.

Never. It stays the same length all the time.

B. At midday, when the sun is directly overhead
Explanation
At midday, when the sun is directly overhead, the shadows are the shortest because the sun is at its highest point in the sky. When the sun is directly overhead, the angle between the sun and any object on the ground is at its smallest, resulting in shorter shadows. As the sun moves lower in the sky during morning or evening, the angle between the sun and objects on the ground increases, causing shadows to become longer. Therefore, the shortest shadows are formed at midday when the sun is directly overhead.

### Does light travel in a straight line?

• A.

True

• B.

False

A. True
Explanation
Light travels in a straight line because it is a form of electromagnetic radiation that propagates as waves. These waves move in a straight path until they encounter an obstacle or medium that causes them to change direction. This phenomenon is known as rectilinear propagation, and it is one of the fundamental properties of light.
