Question

if light travels from oil (slower medium) to water (faster medium) at an angle what happens to the direction of the light ray in water with respect to normal

Answer 1

When light travels from a slower medium to a faster medium, it undergoes refraction and changes direction. In this case, when light travels from oil to water at an angle, it will bend towards the normal.

Step-by-step explanation:

When light travels from a slower medium, such as oil, to a faster medium, such as water, it undergoes refraction. Refraction occurs because the speed of light changes when it enters a different medium. The change in speed causes the light to bend or change direction. In this case, as light travels from oil to water at an angle, it will bend towards the normal, which is a line perpendicular to the surface of the water.
