Question

cos 12° cos 24° cos 36° cos 48° cos 72° cos 84°​

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. This is also known as Snell's law of refraction.
