A light source is placed in the middle of a surface of a swimming pool at depth of 2 m . If the refractive index for the water is (1.33) and the surface of the swimming pool is squared shaped with a length of 2 m , what is the angle of refraction of the light ray ( coming out of the pool ) to the air if the refractive index of the air is 1.

are there options? cause you ain’t. real specific

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
