How many laws of reflection of light are there?  

The correct answer is 2.

Explanation:

• Imagine a ray of light striking a smooth, polished surface, such as a mirror.
• Instead of absorbing the light, the surface reflects it. 
• This phenomenon is known as the reflection of light. 
• The incoming light ray called the incident ray, strikes the surface and is then reflected off as the reflected ray. 
• A perpendicular line drawn on the reflecting surface at the point of incidence is known as the normal ray.
• The principles governing the reflection of light are encapsulated in two laws of reflection. They are as follows:
  • The first law of reflection states that the incident ray, the reflected ray, and the normal to the surface of the mirror, all lie in the same plane.
  • The second law of reflection states that the angle of reflection is equal to the angle of incidence. 

Thus, there are 2 laws of reflection of light.
