Question

formula for refractive index and absolute refractive index​

Answer 1

Explanation:

n=c/v

different mediums have differ values of refractive indeces

Answer 2

Answer:

Formula of refractive index is Sin I/ Sin R

Refractive index is also equal to the velocity of light c of a given wavelength in empty space divided by its velocity v in a substance, or n = c/v.
