Test: Light & Shadow - 2 - Class 5 MCQ

During a total lunar eclipse, the Earth's shadow completely covers the moon.

The duration of a lunar eclipse can be as short as a few minutes or as long as a few hours.

A shadow is formed when there is a source of light, something that blocks the light coming from the source, and a surface for the shadow to form on.

A shadow is always black, regardless of the color of the object blocking the light or the surface the shadow falls on.

Green plants prepare food using sunlight in a process called photosynthesis.

he size of a shadow depends on the distance between the source of light and the object blocking the light. When the distance is more, the shadow is smaller, and when the distance is less, the shadow is bigger.

A transparent material allows almost all light to pass through it.

Metal is opaque, meaning it does not allow any light to pass through it.

When light falls on a picture, part of it bounces off the picture. This bouncing off of light is known as the reflection of light. It is this reflected light that enters our eyes, allowing us to see the picture.
