what is refraction? please answer class-6
Answers
Answer:
In physics, refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction.
Answer:
Refraction is the bending of a wave when it passes from one medium to another. The bending is caused due to the differences in density between the two substances.
“Refraction is the change in the direction of a wave passing from one medium to another.”
Refraction of light is one of the most commonly observed phenomena, but other waves like sound waves and water waves also experience refraction. Refraction makes it possible for us to have optical instruments such as magnifying glasses, lenses and prisms. It is also because of the refraction of light that we are able to focus light on to our retina.
