WebLight is an electromagnetic wave and therefore it travels in the form of a wave. However, the wavelength of light is very small. Hence, a light wave is approximately taken as a ray that travels in a straight line. The wave property of light can be observed only when it interacts with objects having a size comparable to the wavelength of light.
