Applications of Refraction of Light
Refraction has many wide and common applications in optics and also in technology. A few of them are given below:
- A lens uses the refraction phenomenon to form an image of an object or body for various purposes, such as magnification.
- Spectacles that are worn by people with defective vision use the principle of refraction.
- Refraction is used in peepholes of the house doors for safety, in cameras, inside movie projectors, and also in telescopes.
Refraction of Light
Refraction is an important term used in the Ray Optics branch of Physics. Refraction of light is defined as the change in direction or the bending of a wave passing from one medium to another due to the change in speed of the wave. Some natural phenomena occurring in nature where refraction of light takes place are the twinkling of stars, the formation of mirages and Rainbows, Optical illusions, and many more. The major cause of refraction to occur is the change in the speed of waves in different mediums, which is different due to the difference between the densities of the mediums. e.g. the speed of light in a vacuum is maximum. Snell’s Law provides a quantitative description of the amount of bending of a wave, that depends on the refractive index of the two mediums. Let’s learn more about refraction like the Laws of Refractions, Causes of Refraction, Types of Refraction, Examples, and Applications of Refractions in the article below.
