Question

Formation of shadows can be explained by
A) rectilinear propagation of light B) reflection C) refraction D) total internal reflection

Answer 1

Explanation:

A) rectilinear propergation of light

Answer 2

Answer:

A) Rectilinear Propagation of Light

"A piece of Additional Information " :-

• Formation of shadow -

Shadows are always formed on the opposite side. Transparent objects cannot form a shadow. They are only formed in opaque or translucent objects. If we take a glass slab, no shadow is formed because it allows light to pass through it.

• Rectilinear Propagation of Light -

Rectilinear propagation describes the tendency of Electromagnetic waves (light) to travel in a straight line. Light only deviates from a straight line when the medium it is travelling through changes density. This is called refraction.
