The bending of a light ray as it moves from one medium to another is known as refraction. This phenomenon is governed by Snell’s law , which posits that the ratio of the sine of the angle of incidence to the sine of the angle of refraction remains constant. In this article, we will conduct an experiment to trace the path of a light ray as it passes through a rectangular glass slab.
The purpose of our experiment is to trace the path of a light ray as it travels through a rectangular glass slab at various angles of incidence. We will measure and interpret the angle of incidence, angle of refraction, and angle of emergence.
Theory
What are the laws of refraction?
The laws of refraction are as follows:
The incident ray, the refracted ray, and the normal at the point of incidence all lie in the same plane.
According to Snell's law, the ratio of the sine of the angle of incidence to the sine of the angle of refraction remains constant.
What does refraction of light mean?
Refraction of light refers to the bending of a light ray as it moves from one medium to another.
Can you explain lateral displacement?
Lateral displacement is the shift in the path of a light ray perpendicular to the direction of propagation as it emerges from the refracting medium.
