Question

what is relative refractive index??​

Answer 1

Answer:

Relative refractive index is the refractive index of any medium A ( say water ) with respect to that of any other medium B ( say glass). Absolute refractive index is refractive index of any medium with respect to AIR or VACUUM.

hope it will help u

Answer 2

• The ratio of the speed of light in a vacuum to the speed of monochromatic light in the substance of interest. That ratio should be called a relative refractive index. The ratio of the first value to the second one is about the relative refractive index of the glass.
