Question

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

• A. True
• B. False

Answer 1

The correct option is B False

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