Define Refraction of light?

1.	Define Refraction of light?
Answer» Refraction of light is a phenomenon of light in which light rays bend while traveling through obliquely (not normal) rarer medum to denser medium and vice versa.. Refraction is the bending of a wave when it enters a medium where its speed is different. Refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction.
