A light travels from air into water, the angle of refraction is `25^@` to the normal. Find the angle of incidence. Refractive index of water is 1.33 . `mu_a =1`

The refractive index of water is

What is the refractive index of water ?

When a ray of light passes from air into glass, is the angle of refraction greater than or less than the angle of incidence?

When light travels from rarer to denser medium, the refracted ray is _______ the normal.

Refractive index of Ice : 1.31 : : Refractive index of Water : ……………

The ratio of sine of angle of incidence to the sine of angle of refraction.

Light traveling from a transparent medium to air undergoes that internal reflection at an angle of incident of 45^(@) . Then refractive index of the medium may be

Light falls from glass ( mu = 1.5) to air. Find the angle of incidence for which the angle of deviation is 90^@ .

If the angle of incidence is equal to critical angle, then the angle of refraction is
