when a light ray is reflected from a mirror, will its amplitude change
if yes then how

Hmm,yes.
U cannot have perfect reflection/refraction in practical cases.
When a light ray undergoes reflection, some of its part is refracted and the rest part is reflected. So the intensity(amplitude) of light decreses slightly.

The quality of a person's life is in direct proportion to their commitment to excellence, regardless of their chosen field of endeavor.
It is during our darkest moments that we must focus to see the light.

considering wave as light its amplitude will change as there will be
a extra path difference of 90 degrees..
