The polarising angle for transparent medium is θ , v is the speed of light in that medium. Then the relation between θ and v is ( c = velocity of light in air)
Options
- Aθ = tan - 1 v c
- Bθ = cot - 1 v c
- Cθ = sin - 1 v c
- Dθ = cos - 1 v c
Correct answer
B. θ = cot - 1 v c
Step-by-step solution
tan θ = μ = c v ∴ cot θ = v c ∴ θ = cot - 1 v c
