what are the laws of refraction?​

Answer 1

Answer:

The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection.

Answer 2

Answer:

$law \: of \: reflection$

• First law : The incident ray, the reflected ray and the normal at the point of incidence, all lie in the same plane.
• Second law : The angle of reflection (∠r) is always equal to the angle of incidence (∠i). ... You will see that in each case, the angle of incidence (∠i) equals the angle of reflection (∠r)

Explanation:

$law \: of \: refraction$

• 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.
