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 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.
