A linearly polarized light is incident into the air from a high refractive index glass. The refractive index of glass is n,.calculate (20 noints) à) The minimum incident angle for

the light beam 100% reflected b) The required polarization direction so that the light can be 100% transmitted? c) The incident angle so that the incident light can be 100% transmitted. d) If the incident angle is 45 deg and the incident wavelength is A = 0.5 pm, what will be the penetration depth?
