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.

Reflection of Light

The process due to which the light rays fall on the surface, and get bounced back is known as a reflection of light. Light is recognized for its highly predictable behaviour. The behaviour of a ray of light as it reflects would satisfy a definite law known as the law of reflection if it could be seen approaching and reflecting off of a flat mirror. The law of reflection is shown in the diagram below....

Laws of Reflection at Plane Surfaces

A plane mirror refers to a mirror with a flat (planar) reflective surface. The light rays when striking a plane mirror, the angle of reflection equals the angle of incidence always. The angle of the incidence refers to the angle between the incident ray and the surface normal (an imaginary line perpendicular drawn to the surface). In a similar way, the angle of reflection is the angle between the reflected ray and the normal at the point of incidence....

Laws of Reflection at Rough Surfaces

When light reflects from a rough surface in an irregular pattern, it is known as irregular or diffused reflection. Let’s use an example to better grasp this. Imagine that a wall is illuminated. Parallel light rays will not reflect in a parallel pattern. Diverse directions are where the light that reflects spreads. The law of light reflection is at work here as well....
