Question

write laws of refraction​

Answer 1

Answer:

Laws of refraction state that: The incident ray, reflected ray and the normal, to the interface of any two given mediums; all lie in the same plane. The ratio of the sine of the angle of incidence and sine of the angle of refraction is constant.

Answer 2

Answer:

1)If Incident Ray Is Parallel to Principal axis after refraction passes through principal focus.

2) If Incident Ray passes through principal focus after refraction It is parallel to principal axis.

3) If Ray passes through optical centre after refraction it does not passes through anything it goes straight .
