When light wave passes from a medium of refractive index '\(\mu\)' to another medium of refractive index '\(2 \mu\)' the phase change occurs to the light is :
- A zero
- B 90\(^\circ\)
- C 60\(^\circ\)
- D 180\(^\circ\)
Answer & Solution
Correct Answer
(A) zero
Step-by-step Solution
Detailed explanation
When light passes (transmits) from one medium into another, the transmitted wave undergoes no phase change, regardless of whether it enters a denser or rarer medium. A phase change of \(180°\) occurs only during reflection at a boundary with a denser medium — not during…
