Question

Light enters water at an angle of incidence of 24 degrees and refractive index of 4/3.Calculate the angle of refraction

Answer 1

Step-by-step explanation:

According to Snell's law :

Sin i / Sin r = refractive index

`r = sin^( - 1) ( (sin \: i)/(1.33) ) = sin^( - 1) (0.3)`

`angle \: of \: refraction = 17.45°`

Therefore, angle of refraction is less than angle of incidence because the light ray bends towards the normal when it travels from rarer to denser medium
