Question

The rectilinear propagation of light in a medium is due to
A) its large wavelength B) its high frequency C) its large velocity D) refractive index of the medium Not Available

Answer 1

hey!!

here is ur answer!!

==================================

As we all know,

The property of light of traveling in straight lines is called rectilinear propagation of light.

For example : When you shine a torch in the dark, Light appears to go straight outwards.
This observation shows that light travels in straight line.

Now, Frequency of light depends on the source of a light travelling in a medium Do therefore

The correct answer will be frequency.. that is its high frequency...
