Detailed explanation-1: -Light does not travel in a straight path. It travels as a wave. However as the wavelength is very small, it looks like it travels in a straight line. Also when light travels from one medium to another, it bends.
Detailed explanation-2: -Light Travels in Straight Line Examples are as Follows: Light comes out from a torch or train or lamp follows a straight line path. A straight line path of light is visible when Sunlight comes out through the small holes in a dusty atmosphere.
Detailed explanation-3: -Light is produced by a source and travels outwards from the source in straight lines and all directions at 300, 000 km/s. Because we can’t actually see light travelling, we depict this property in diagrams that show light travelling in straight lines called rays.
