NEET Physics Light Propagation MCQ Question
When light propagates through a material When light propagate permittivity εᵣ and relative medium of relative the velocity of light, v is given permeability μᵣ, the light in vacuum) by: (c = velocity of light in vacuum)
v = √(μᵣ/εᵣ)
v = √(εᵣ/μᵣ)
v = c/√(εᵣμᵣ)
v = c
Correct Answer
Detailed Explanation
The velocity of light in a medium is given by v = c/√(εᵣμᵣ), where εᵣ is the permittivity and μᵣ is the permeability of the medium.
