Refractive index of water with respect to air is `sqrt(2)`. Alight ray is incident on the surface at an angle 30° travelling through water. The deviation of light ray is

The refractive index of a medium with respect to air is sqrt2 . If the angle of incidence of a ray of light in air is 45^@ determine the angle of deviation for that ray in case of refraction.
