Question

What is propagation of light ??

Answer 1

Propagation of light refers to the manner in which an electromagnetic wave transfer it's energy from one point to another. Three main processes generally occur when light passes between boundaries from one medium to another:
Transmission.
Reflection.
Refraction.

Answer 2

 The traveling of the light is termed the propagation of light.

• Type of energy that can be seen with the human eyes is called light.
• And the light's propagation means the way that energy moves from one point to another.
• A straight line is the travel path of light usually.
• Transmission, reflection, and refraction are the major process that happens when light moves from one medium to another.
