Question

Whenever light falls on an opaque object, a shadow always appears on the background.

• A. True
• B. False

Answer 1

The correct option is B False

Whenever light falls an opaque object, a shadow is formed but it's not necessary that it is observable. If the beam of light falls parallel to the screen, the shadow is not observed. Shadows are observed on the screen when the angle that the screen, the object, and the source make is greater than 90 degree.
