No, the law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection. Therefore, if angle of incidence is 300 then according to the law of reflection angle of reflection will also be 300. Now, summing both the angles will not give us 900.

Most recent answer: 10/22/2007 When light hit a mirror, does it reflect off at a 90 degree?- teckkian (age 12) Tampines North Primary School, SIngapore Teckkian - No, light will not necessarily be reflected off a mirror at a 90 degree angle. When light is reflected by a mirror, it ’bounces’ off at the same angle from the mirror that it came in at. It’s like this: (published on 10/22/2007) Follow-up on this answer
Translation: A ray of light comes down at an angle and is reflected off a surface, for example a mirror. From that point we can imagine a line straight up, at 90 degrees to the surface, called the normal. The angle of reflection is measured from the normal, which is 0 degrees, to the ray of reflected light. |
Is angle of reflection always 90 degrees?
