Refraction of Water Waves
In physics refraction is the redirection of a wave as it passes from one medium to another. Refraction of light occurs because of this change in the speed of light due to a change in the medium. Wave Refraction Light travels through water with a speed of 225 x 108 ms. . These values for the angle of incidence and refraction are. When light enters an optically denser medium from an optically rarer medium the speed of light slows down and light bends towards the normal. Refraction of light is the most commonly observed phenomenon but other waves such as 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 our retina. Light waves change speed when they pass across the boundary between two substances with a different density such as air...
