The glass slab experiment is a classic physics experiment used to study the behavior of light as it passes through different mediums. Here are the details of the experiment:

Aim:
To determine the refractive index of a glass slab.

Observation:
As the angle of incidence increases, the angle of refraction also increases.
The incident ray, refracted ray, and the normal line all lie in the same plane.

Analysis:
The experiment demonstrates the bending of light as it passes from air into the glass slab and then from the glass slab back into the air. By measuring the angles of incidence and refraction, you can use Snell’s Law (refraction, you can use Snell’s Law (n1 sin(I)= n2 sin(r))
to calculate the refractive index (n)
Of the glass slab.

Remember, the refractive index of a medium indicates how much the speed of light is reduced in that medium compared to its speed in a vacuum.
