Question

According to the law of reflection, a light ray striking a mirror at an angle of incidence of 30 degrees will leave the mirror at an angle of

1) 30 degrees
2) 45 degrees
3) 60 degrees
4) 90 degrees

Answer 1

According to the law of reflection, a light ray striking a mirror at an angle of incidence of 30 degrees will leave the mirror at an angle of 30 degrees.

Step-by-step explanation:

The law of reflection states that the angle of reflection equals the angle of incidence when a light ray strikes a smooth surface, such as a mirror.

In this case, the light ray is striking the mirror at an angle of incidence of 30 degrees. According to the law of reflection, the light ray will leave the mirror at the same angle of 30 degrees.

Therefore, the correct answer is option 1) 30 degrees.
