   Refraction definition is - deflection from a straight path undergone by a light ray or energy wave in passing obliquely from one medium (such as air) into another (such as glass) in which its velocity is different. Did You Know?

   Jun 17,  · A refraction test is what the doctor uses to get your eyeglasses prescription. You look at a chart, usually 20 feet away, or in a mirror that makes things look like they’re 20 feet away.

   Refraction, in physics, the change in direction of a wave passing from one medium to another caused by its change in speed. For example, waves in deep water travel faster than in shallow. If an ocean wave approaches a beach obliquely, the part of the wave farther from the beach will move faster.

   Refraction is a test that optometrists and ophthalmologists use to determine what lens prescription you need in order to have normal 20/20 vision.

   Refraction is the change of direction of a wave when it travels from a medium in which it has one velocity to a medium in which it has a different velocity. Refraction of sound occurs in the ocean because the temperature or the water changes with depth, which causes .
