Cat and mouse shadows

The video tutorial explains how shadows are formed when an object blocks light, causing the shadow to take the shape of the object. It further explores how the length of a shadow can vary depending on the angle of the light source. For instance, a mouse's shadow can appear longer than a cat's when the light is at a low angle, while the cat's shadow is shorter due to a high light angle. This illustrates the relationship between light angles and shadow lengths.

What question is posed about shadows in the introduction?

• Why do shadows change color?

• What makes shadows disappear?

• How can a mouse's shadow be longer than a cat's?

• Why are shadows always shorter than the objects?

How are shadows formed?

• When an object reflects light

• When an object absorbs light

• When an object blocks the path of light

• When an object emits light

What determines the shape of a shadow?

• The color of the object

• The shape of the object

• The distance from the light source

• The intensity of the light

What happens to a shadow when the light source is at a high angle?

• The shadow becomes longer

• The shadow becomes shorter

• The shadow changes color

• The shadow disappears

Why can a mouse's shadow be longer than a cat's?

• Because the cat blocks less light at a high angle

• Because the cat is further from the light source

• Because the mouse blocks more light at a low angle

• Because the mouse is closer to the light source
