The video tutorial explains how shadows are formed when an object blocks light, resulting in a shadow that mirrors the object's shape. It discusses how the length of a shadow can vary depending on the angle of the light source. A lower angle causes longer shadows, while a higher angle results in shorter shadows. This concept is illustrated by comparing the shadows of a mouse and a cat, showing that a mouse's shadow can be longer than a cat's under certain lighting conditions.

What question is posed about the shadows of a mouse and a cat?

• Why is the mouse's shadow always shorter?

• How does the cat's shadow disappear?

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

• Why do both shadows have the same length?

What determines the shape of a shadow?

• The distance from the light source

• The shape of the object

• The color of the object

• The size of the object

How does light travel to create shadows?

• In straight lines

• In curved lines

• In circular paths

• In zigzag patterns

What happens to a mouse's shadow when the light is at a low angle?

• It becomes shorter

• It disappears

• It becomes longer

• It stays the same

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

• Because the mouse is larger

• Due to the angle of the light source

• Because the cat is transparent

• Due to the color of the mouse
