Question

if the critical angle if medium is sin-1(3/5)find the polarising angle

Answer 1

If i is polarizing angle and c is critical angle for a medium, taking other medium as air for which refractive index=1, then the two are related via expression
tani=1/ sinc ...........(1)
⇒i=tan−1 (1/sinc)

Here c= sin-1(3/5)

now putting value in the relation
we get

i =tan-1(1/sin(sin-1(3/5)))
i =tan-1(5/3)

so the polarising angle is tan-1(5/3)

Hope it helps you

Answer 2

If the critical angle if medium is sin(3/5) find the polarising angle - - - - - - -
