23 lip 2023 · Sound is like light in some ways: it travels out from a definite source (such as an instrument or a noisy machine), just as light travels out from the Sun or a light bulb. But there are some very important differences between light and sound as well.
5 gru 2019 · Sound received by our human ears and light received by our human eyes may often seem to be two parts of the same phenomenon, but they are actually quite distinct. Sound waves are longitudinal waves that can travel through air at about 343 m/s. Light waves are EM radiation and travel at 3 × 10^8 m/s.
Light and sound are two different things, but there are a few effects that involve their interaction. Three effects were discussed: the photoacoustic effect, the acousto–optic effect, and sonoluminescence. The photoacoustic effect involves a sound emission that originates from a change in density induced by light.
During a lightning strike, the air gets very hot. For this reason, it becomes a source of light as well as sound. The difference between the speed of sound and light means that we first see the lightning flash and only then hear the thunder that accompanies a discharge.

Light is a transverse, electromagnetic wave that can be seen by the typical human. The wave nature of light was first illustrated through experiments on diffraction and interference. Like all electromagnetic waves, light can travel through a vacuum. The transverse nature of light can be demonstrated through polarization.
