You see a fish in the water at an apparent depth of 1.83 m. the actual depth of the fish, if the index of refraction of the water relative to air is 4/3, must be 2.44 m.
Refraction, in physics, is the alternate route of a wave passing from one medium to any other because of its change in pace. as an example, waves journey faster in deep water than in shallow.
In physics, refraction is the redirection of a wave as it passes from one medium to some other. The redirection can be because of the wave's trade-in pace or by using a change in the medium.
Refraction is the bending of light (it also occurs with sound, water, and different waves) as it passes from one obvious substance into every other. This bending by using refraction makes it viable for us to have lenses, magnifying glasses, prisms, and rainbows. Even our eyes depend upon this bending of light.
