Question

write second law of refraction​

Answer 1

Second law of refraction states that for two given media, the ratio sinisinr=constant s i n i s i n r = c o n s t a n t , where i is the angle of incidence and r is the angle of refraction. Refractive index (n) of a medium is given by n=sinisinr.

Answer 2

Answers : According to the second law of refraction , ration of the sine of angle of incidence I to the sine of angle of refraction r is always constant for a given wave length of light of sine r sine i are constant also called snell's law ....
