Question

HEy guys.plz help with this....
a) State the law of refraction of light that defines the refractive index of one medium with respect
to the other.
b) Express it mathematically also.
c) Write the expression relating the refractive index of medium A‘ with respect to the medium B‘ to the speed of light in the two media A‘ & B‘. Name the constant when medium B‘ is a vacuum.

Answer 1

Answer:it is the snell's law

Ratio of sine of angle of incidence to the sine of angle of refraction is a constant ,which is the refractive index

B) sine i/sine r= refractive index

C) refractive index of medium A with respect to medium B =speed of light in medium B/speed of light in medium A

Constant is absolute refractive index.
