Question

define absolute refractive index​

Answer 1

Hey mate!

Thank you for asking this question! ❤

Answer:

___________________________________________________

• The Absolute Refractive Index of an optical medium is defined as the ratio of the speed of light in vacuum to the speed of light in that medium. It is numerically also equal to the ratio of the sine of the angle of incidence in vacuum, to the sine of the angle of refraction in that medium...
• The Relative Refractive Index of a second medium with respect to a corresponding first medium is defined as the ratio of the speed of light in the first medium, to the speed of light in the second medium...
