Question

laws of refraction and reflection​

Answer 1

the turning back of light rays on the surface called as reflection

the change in medium by light rays called as refraction

Answer 2

hey mate here is your answer ♥

laws of refraction are:

the three laws of refraction are as follows :

first Law of refraction state that incident ray, refracted ray and the normal at the point of incidence all lies in a same plane

second Law states that angle of incidence and angle of refraction is constant which is known as Snell's law

law of reflection are :

the law of reflection states that the incident ray, the reflected ray and the normal to the surface of the mirror all lie in the same plane, the angle of reflection is equal to the angle of incidence

hope this helps you dear ♥
