Answer» (a) The angle between the mirror and the incident ray is 30 degrees. The sum of the angle of incidence and this angle (30) MAKES a RIGHT angle. So, the angle of incidence is 90 - 30 = 60 degrees. As the angle of incidence and the angle of REFLECTION are equal, both angles equal 60 degrees.Explanation:Hope so you are satisfied with the answerIf so PLEASE follow....... |
