1 the combination of two or more electromagnetic waveforms to form a resultant wave in which the displacement is either reinforced or cancelled.
2 the light ray strike on the surface .
3 when the light pass through One medium to another medium or rare medium to denser medium then it change its direction is called in
Refraction.
4 the point where incident strike is called point of incidence .
5 normal is the line which is perpendicular to the surface .
6 the angle between the incident ray and the normal ray is called angle of incidence .
7 the ray pass rare medium to denser medium with bend towards normal or further from normal to form an angle called reflection of light .
8. the angle between incident ray and the emergent ray is called angle of deviation .
