Question

Which of the following material forms a shadow when light falls on it?

• A. Wooden block
• B. Glass
• C. Cloth
• D. Tracing paper

Answer 1

The correct option is A Wooden block

The materials through which light cannot pass are called opaque.
When light falls on an opaque object, some part of the light gets absorbed and the other part gets reflected back. This reflected light forms a shadow.
For example:- wooden block, paper, etc.
