Question

Write three applications of rectilinear propagation of light?

Answer 1

Drawing the diagram of the situation:

Rectilinear propagation of light:

1. In a given medium, light travels in straight lines. This is known as rectilinear propagation of light.
2. Due to the property that light travels in straight lines shadows are formed.

Application of rectilinear propagation of light:

1. Propagation of light in pinhole cameras.
2. The formation of shadows.
3. Formation of eclipses.
