NEET 2022 Physics Speed of Light in Medium MCQ Question
Type: MCQ-conceptual-Medium-Class 12
When light propagates through a material medium of relative permittivity εᵣ and relative permeability μᵣ, the velocity of light, v, is given by: (c-velocity of light in vacuum)
A
v = c/√(εᵣμᵣ)
B
v = c/√(εᵣμᵣ)
C
v = c
D
v = μᵣ/√(εᵣ)
Correct Answer
Option A
Detailed Explanation
The velocity of light in a medium is given by v = c/√(εᵣμᵣ), where c is the speed of light in vacuum.
