Question

Find the refractive index of the liquid.

Answer 1

Step-by-step explanation:

In optics refractive index is a dimensionless number of medium , that informs about how the ray of light travels through that medium. Refractive indices are different for different mediums.

it is given by

`n=(v)/(c)`

n= refractive index of the medium

v= velocity of light in that medium and

c= velocity of light in vacuum.

n=1.33 for water,meaning the speed of light in vacuum is 1.33 times the speed of light in water.

R.D. also defines how much did the light bend travelling from one medium to the other, because when light travels from one medium to the other it changes its direction.

also, from snell's law we can find out the refractive index of any material

which says

`n= (sin i)/(sin r)`

i= angle of incidence and

r= angle of refraction.
