Question

Philoid · Accepted Answer

The light from the torch “C” will not form a shadow on the screen because the light always travels in the straight line due to which the light from “C” will go downward. Also the shadow is formed on the path from which the light is coming but there is no screen (Or opaque object) on downside to take the shadow, hence we will not get shadow from the torch “C”.
