Question

state the refractive index of aim
​

Answer 1

Answer:

In optics, the refractive index (also known as refraction index or index of refraction) of a material is a dimensionless number that describes how fast light travels through the material. It is defined as

n= c/v

where c is the speed of light in vacuum and v is the phase velocity of light in the medium. For example, the refractive index of water is 1.333, meaning that light travels 1.333 times as fast in vacuum as in water. Increasing refractive index corresponds to decreasing speed of light in the material.

Answer 2

Answer:

The Aim is to trace the path of a Ray of light passing through a rectangular glass slab for different angles of incidence .Measure the angle of incidence, angle of refraction, angle of emergence and interpret the result.
