When a light wave reflects off a mirror, it must obey the law of reflection. Answer: A surface which reflects the light is called reflector. Thus, if the angle of reflection θ 1 (angle of reflection) is equal to the alignment of the dipoles (90 - θ 2), where θ 2 is angle of refraction, no light is reflected. This is because interior angles of triangles add to 180° 180 °. Answer:The angle reflection will be 22 degrees. Or to prolong what was already unbearable."
