Question

Which of the following objects will cast a shadow?

• A. Wax paper
• B. Water in a glass
• C. Wooden chair
• D. Coloured window glass

Answer 1

The correct option is C Wooden chair

For a shadow to be formed, the light should be obstructed by the object so that the screen behind it stays dark.
Therefore to form a shadow, the object should be opaque.

Wax paper and coloured window glass are translucent objects, so will not form shadow.

Water in a glass is translucent, so it will not form a shadow.

Wooden chair is opaque, hence it will form a shadow.
