FAQs based on Refraction of light
Question 1: Define the term Refraction.
Answer:
The change that occurs in the direction of a wave when light passes from one medium to the other is known as refraction of light.
Question 2: When is the refraction of light not possible?
Answer:
When the light is incident perpendicular to the boundary or surface, refraction of light is not possible.
Question 3: What is the difference between reflection and refraction in light?
Answer:
The bouncing back of light when it strikes a smooth surface is called Reflection. While the bending of a light ray when it travels from one medium to other is called refraction of light.
Question 4: Give an example of the Refraction of light.
Answer:
There are many examples of refraction of light observed in our daily life like the Twinkling of stars. The Twinkling of stars is because of the atmospheric refraction occurs by the light from the star undergoing a gradual change in the medium.
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.
