Question
What happens to a light wave when it is reflected off the surface of a material with a higher index of refraction?
It reflects with its phase shifted by .
The phase shift is proportional to the angle of reflection.
It reflects with its phase unshifted.
It reflects with its phase shifted by /2.
The phenomenon whereby two waves cancel each other is called
subtraction.
negative addition.
interference.
diffraction.
a.It reflects with its phase shifted by .
b.The phase shift is proportional to the angle of reflection.
c.It reflects with its phase unshifted.
d)It reflects with its phase shifted by /2.
Explanation / Answer
1. answer b (because phase gets shifted by (180-r) here r is angle of reflection
2. answer c
