Question

The angle of polarisation for any medium is 60o . The criticle angle for same medium at air interface will be:- (A) (sin)- 1((1/√3)) (B) (sin)- 1(.√3.) (C) (cos)- 1(.√3.) (D) (cos)- 1((1/√3))

μ =tanip=√3 ⇒ (θ )c=(sin)- 1((1/μ )) ⇒ (θ )c=(sin)- 1((1/√3)) .

Q. The angle of polarisation for any medium is $60 o$ . The criticle angle for same medium at air interface will be:-

$(s in)^{- 1} (\frac{1}{3})$

$(s in)^{- 1} (3)$

$(cos)^{- 1} (3)$

$(cos)^{- 1} (\frac{1}{3})$

$μ = t an i_{p} = 3$ $\Rightarrow$ $(θ)_{c} = (s in)^{- 1} (\frac{1}{μ})$ $\Rightarrow$ $(θ)_{c} = (s in)^{- 1} (\frac{1}{3})$ .
