# State the Relation Between the Critical Angle and the Absolute Refractive Index of a Medium. - ICSE Class 10 - Physics

ConceptTotal Internal Reflection - Critical Angle

#### Question

State the relation between the critical angle and the absolute refractive index of a medium.

#### Solution

mu = 1/(sin c) or sin c = 1/muwhere ‘c’ is the critical angle and ‘μ’ is the absolute refractive index.

Is there an error in this question or solution?
