Question

Introduction for Refraction of light at a plane surface​

Answer 1

Explanation:

hello!!!!

refraction in a plane is a simple custom that ..

a ray of light passing through a deviiation and formong an angle!!

ray of light (i) incident on a surface makes an angle (r) of refraction whic may be mlre lr less than that!!

thanks!!!

Answer 2

Explanation:

Refraction of light are divided into 6 categories they are:

1. Incident ray- The ray of light which fall on the surface.
2. Reflected ray- This ray bounce back into the same medium after sticking the reflecting surface.
3. Point of incidence- The point of the mirror surface where the incident ray strikes and reflected ray bounce off.
4. Normal ray -It is the line drawn perpendicular to the reflecting surface at the point of incidence.
5. Angle of incedence- The angle between incident and normal.
6. Angle of reflection- The angle between normal and reflected ray.
