what is the cause of refraction ? Due to refraction many events and effects are visible in our daily life.write any four of them
Answers
Answer: Good Question!
Explanation:
Refraction is the phenomenon of bending of light at the boundary of two mediums. Refraction is caused due to the change in speed of light when it enters from one medium to another.when light goes from water to air it bends away from the normal because three is an increase in speed of light.
An example of refraction is a bending of the sun's rays as they enter raindrops, forming a rainbow.
Refraction of light can be seen in many places in our everyday life. It makes objects under a water surface appear closer than they really are. It is what optical lenses are based on, allowing for instruments such as glasses, cameras, binoculars, microscopes, and the human eye.
Answer:
The change in the path of light from rare to denser or denser to rarer is refraction and it depends on density of the medium,refractive index and color or wavelength of light.
