Which term refers to the bending of light rays when they encounter the edge of a barrier?A interferenceB reflectionC refractionD diffraction

he refraction of light is the bending of light rays as they pass from one medium to another, thereby changing the path of the rays. Refraction occurs due to a change in the speed of the light ray or wave. [1] The speed of light is greatest in a vacuum.17 Jul 2023
