Did light travels in Straight Path?

Light don't travel in a straight path/line, It moves in waves. But, due of the extremely short wavelength, it appears as though it is travelling straight ahead. Moreover, light bends when it moves from one medium to another. Light travels in straight lines mostly because it is a wave and prefers to cover the shortest path between two places. Yet, certain impediments might cause light to deviate from a straight path. This phenomenon is frequently referred to as diffraction.
