Dec 5, 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.
Jan 12, 2024 · Light is electromagnetic radiation visible to human eyes, while sound is a mechanical wave that travels through mediums like air or water.

Light waves are electromagnetic waves that can be seen by the human eye. They are a form of radiation and are created when electrons are excited and revert to a lower energy state, therefore causing the release of protons. Electromagnetic waves like light waves do not require a medium to travel through, which means that they can pass through a vacu...
Sound waves are mechanical waves and are created by the vibration of objects or matter. These vibrations cause pressure, and it is the waves of pressure that can be heard. Sound waves need some form of medium to be able to propagate and they cannot travel through a vacuum, hence the saying that nobody can hear you scream in space.
Light and sound waves are two forms of waves that can be reflected, refracted, and diffracted. However, while light is an electromagnetic wave, sound is a mechanical wave. Light waves are created by the excitement of electrons and sound waves are formed when a medium vibrates. Featured Image Credit: (L) Jan Huber, Unsplash | (R) Ritupon Baishya, Un...
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.
Finally, we need to say two things about light perception. For sound, intensity (proportional to amplitude-squared) is perceived as loudness, and for light it is brightness. For sound, frequency is perceived as pitch, and for visible light it is perceived as color.
The very large difference between the speed of light and the speed of sound explains why you: See lightning before you hear it. See a distant firework explode before you hear it.
Jul 23, 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.
