1.	The critical angle of a transparent crystal for greeen light is 30 degree .find the angle of polarisation of that crystal?
Answer» We know, RELATION between polarising ANGLE and CRITICAL angle. e.g., $\boxed{\bf{tani=\frac{1}{sinC}}}$ Where i is angle of polarisation and C is the critical and of the TRANSPARENT crystal. so, tani = 1/sin30° = 1/(1/2) = 2 i = tan^-1(2) hence, angle of polarisation is tan^-1(2)
