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, such as from oil to water, the light ray bends away from the normal. This phenomenon is known as refraction.

Step-by-step explanation:

When light travels from a slower medium to a faster medium, such as from oil to water, the light ray bends away from the normal. This phenomenon is known as refraction. The amount by which the light ray bends depends on the angle of incidence and the refractive indices of the two mediums.

For example, if the light ray is incident at an angle from oil to water, it will refract away from the normal when it enters the water. The angle of refraction can be calculated using Snell's law: n1 * sin(theta1) = n2 * sin(theta2), where n1 and n2 are the refractive indices of the two mediums, and theta1 and theta2 are the angles of incidence and refraction, respectively.

In this case, as the light ray refracts away from the normal, its direction will change in water compared to its original direction in oil.
