A ray of light is incident on a plane mirror at an angle of 40o with the mirror surface. What will be the angle of reflection?
it will be 40 degrees with the mirror surface, or 50 deg from the normal
To determine the angle of reflection, we can use the law of reflection. According to this law, the angle of incidence is equal to the angle of reflection.
In this case, the angle of incidence is given as 40 degrees. Therefore, the angle of reflection will also be 40 degrees.
