Refraction occurs when a wave that originally traveled through one medium enters a different medium. For example, a sound wave initially moves through the air and then encounters a wall, some sound waves are reflected by the wall, some are refracted by the wall. Refraction means that sound waves are absorbed or transmitted in the wall, but the direction of propagation changes. The change in the direction of propagation occurs because the speed of the sound wave changes when it enters a different medium from the previous medium.<!--more--><\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-size: 12pt; font-family: 'times new roman', times, serif;\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-8086 aligncenter\" src=\"https:\/\/gurumuda.net\/physics\/wp-content\/uploads\/sites\/28\/2023\/02\/Wave-refraction-1.png\" alt=\"Wave refraction 1\" width=\"290\" height=\"243\" srcset=\"https:\/\/gurumuda.net\/physics\/wp-content\/uploads\/sites\/28\/2023\/02\/Wave-refraction-1.png 290w, https:\/\/gurumuda.net\/physics\/wp-content\/uploads\/sites\/28\/2023\/02\/Wave-refraction-1-180x151.png 180w\" sizes=\"auto, (max-width: 290px) 100vw, 290px\" \/><\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; font-size: 12pt;\">The angle between the incident ray and the normal is called the angle of incidence, while the angle between the refracted ray and the normal is called the angle of refraction.<\/span><\/p>\n<p style=\"text-align: justify;\"><span style=\"font-family: 'times new roman', times, serif; font-size: 12pt;\">If the speed of the wave increases when it enters a new medium, the angle of refraction also increases.
