WebLight travels as transverse waves and faster than sound. It can be reflected, refracted and dispersed. Ray diagrams show what happens to light in mirrors and lenses. Eyes and cameras detect light. WebJul 23, 2024 · The simplest phenomenon was the transmission of light in straight lines, as in shafts of sunlight through a cloud or solar eclipses. Such behaviour was expected for a stream of corpuscles, but not for a wave. Water waves rippling from a stone dropped into a pond could be seen to spread in all directions and bend around obstacles to some extent.
WebLight from a stationary source travels at 300,000 km/sec (186,000 miles/sec). Moving Light Light from a moving source also travels at 300,000 km/sec (186,000 miles/sec). Say that Einstein's bike travels at 10% the speed of light (30,000 km/sec): the speed of light from Einstein's headlight does NOT equal 330,000 km/sec. WebThe main reason why light moves in straight lines are because it is a wave and prefers to travel the smallest distance between the two points. Light, however, can diverge from a straight trajectory when it strikes certain obstructions. Diffraction is a …
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.
