A ray of light strikes a plane mirror at an angle of incidence of 30 degrees. What is the angle of reflection?
Correct Answer: 30 degrees
- Step 1: Understand that a ray of light is hitting a mirror.
- Step 2: Identify the angle at which the light hits the mirror, which is called the angle of incidence. In this case, it is 30 degrees.
- Step 3: Remember the law of reflection, which states that the angle of reflection is always equal to the angle of incidence.
- Step 4: Since the angle of incidence is 30 degrees, the angle of reflection must also be 30 degrees.
- Law of Reflection – The angle of incidence is equal to the angle of reflection when light strikes a reflective surface.
