angle between plane mirror and incident ray is 30 degree .what is the angle of reflection? |
| To find out the angle of reflection,we should know the angle of incidence.In this case,the incident ray makes an angle of 300 with the surface of the mirror,so the angle of incidence is not 300.The angle of incidence is the angle between incident ray and normal.So,in this case,the angle of incidence will be 900 - 300 = 600 . Since the angle of incidence is 600 degrees,therefore the angle of reflection is also 600 degree. |
