The angle of incidence at which reflected light is totally polarized for reflection from air to glass (refractive index $$n$$) is

$${\tan ^{ - 1}}\left( {1/n} \right)$$

$${\sin ^{ - 1}}\left( {1/n} \right)$$

$${\sin ^{ - 1}}\left( n \right)$$

An electromagnetic wave of frequency $$v=3.0$$ $$MHz$$ passes from vacuum into a dielectric medium with permittivity $$ \in = 4.0.$$ Then

wave length is halved and frequency remains unchanged

wave length is doubled and the frequency becomes half

wave length is doubled and the frequency remains unchanged

wave length and frequency both remain unchanged. A fish looking up through the water sees the outside world contained in a circular horizon. If the refractive index of water is $${4 \over 3}$$ and the fish is $$12$$ $$cm$$ below the surface, the radius of this circle in $$cm$$
