Uses of Reflection of Light
There are several use cases where the understanding of the reflection of light help, some of those use cases are as follows:
- To prevent parallax mistakes, meters like ammeters and voltmeters use mirrors. The image of the pointer is directly somewhere under the pointer when the reading is taken from that place.
- A convex and a plane mirror, respectively, are used to make a car’s wing and rearview mirrors. The driver can see objects on both sides of the car due to the two wing mirrors. The driver may see objects behind the vehicle due to the rearview mirror.
- A mirror is used in a microscope to reflect light onto the material being examined.
- Dentists also inspect a patient’s teeth using concave mirrors. The teeth appear magnified in the concave mirror.
- Torches and automobile headlamps both use parabolic mirrors as reflectors. To create parallel beams, a tiny bulb is put at the mirror’s focal point.
- As they produce magnified and upright images, concave mirrors with extended focal lengths can be used as shaving or makeup mirrors.

Laws of Reflection
Laws of Reflection is a principle or rule that governs the phenomenon of reflection of light. The law of reflection states that a light ray will reflect off a surface at the same angle that it hit it when it comes into contact with it. The angle at which a light beam strikes a surface is known as the angle of incidence, and the angle at which the beam of light bounces off the surface is known as the angle of reflection. You can always determine how a light ray will behave, i.e., what direction it will go in and at what angle, by observing a single light ray approach and bounce off a flat mirror. In general, this is how the law of reflection works.
Now let us learn more about the Laws of reflection by understanding the concepts like What are the Laws of reflection? its formula, verification of laws of reflection, Laws of reflection for plane and rough surfaces, and examples of them.
