Question: A ray of light strikes a plane surface at an angle of incidence of 30 degrees. What is the angle of reflection? (2023)

Options:

Correct Answer: 30 degrees

Exam Year: 2023

Solution:

According to the law of reflection, the angle of reflection is equal to the angle of incidence. Therefore, the angle of reflection is 30 degrees.

A ray of light strikes a plane surface at an angle of incidence of 30 degrees. What is the angle of reflection? (2023)

Step 1: Understand that when light hits a surface, it can bounce off. This is called reflection.
Step 2: Learn about the law of reflection, which states that the angle at which the light hits the surface (angle of incidence) is equal to the angle at which it bounces off (angle of reflection).
Step 3: Identify the angle of incidence given in the question, which is 30 degrees.
Step 4: Apply the law of reflection: since the angle of incidence is 30 degrees, the angle of reflection must also be 30 degrees.

Law of Reflection – The principle stating that the angle of reflection is equal to the angle of incidence when light reflects off a surface.
