INTRODUCTION:- When a ray of light passes from one medium to another, the ray undergoes a change in direction, that is, it is bent or refracted.angle made by the incident ray with a with a perpendicula perpendicular at the point of incidence is termed the angle of incidence, i while r, made by the refracted ray is termed the angle of refraction.???????????????????????????????????????????????.??????????????????????????????????????
