Question

When light wave suffers reflection at the interface from air to glass, the change in phase of the reflected wave is equal to
(a) 0
(b) $\frac{\pi}{2}$
(c) π
(d) 2π

Answer 1

Hey !!

When light wave suffers reflection at the interface from air to glass, the change in phase of the reflected wave is equal to ''π ''

Option (C)

Good luck !!

Answer 2

Answer:

When light wave suffers reflection at the interface from air to glass, the change in phase of the reflected wave is equal to (c)π.

Explanation:

Whenever a light ray travels from air to glass and reflects from the glass surface, i.e. the one with a higher refractive index, the phase change takes place.

However, in case of the opposite situation in which light gets reflected from the medium with a lower refractive index( air) then phase change is zero.
