write an experiment to show the refractive index of the glass

Answers
Explanation:
When a beam of light falls obliquely at the interface of the two optical media, direction of its path changes when it enters into the other medium. This phenomenon exhibited by the light rays is called refraction of light. This is due to the change in speed of light while going from one medium to the other.

During the refraction, when light travels from one medium to another transparent medium, the speed and wavelength of light changes, whereas frequency remains the same.
When a light ray travels from rarer to denser medium, its speed gets slow down and the ray bends towards normal (∠i >∠r).
When the ray of light travels from denser to rarer medium, its speed goes up and the ray bends away from the normal (∠i < ∠r).
From the above two points, we can conclude that the light bends on undergoing refraction.
Answer:
here is ur answer mate
Explanation:
Draw a normal M1N1 at O2. Join O1 and O2. It will represent the path of ray inside the glass slab, i.e. refracted ray. Repeat the experiment by taking the different angles of incidence such as 45° and 60° on the other part of paper and measure the angle of refraction and emergence accordingly and tabulate them.
