- 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.
May 24, 2024 · We know that light is a wave based on how it behaves – it exhibits the same properties of other waves we have examined – it interferes with itself, it follows an inverse-square law for intensity (brightness), and so on.
16 hours ago · According to Sapienza, this isn't the right question to be asking. "Light is not sometimes a particle and sometimes a wave," he said. "It is always both a wave and a particle. It's just that we ...
Light, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye. [1] Visible light spans the visible spectrum and is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz.

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...
What are light waves? Light is a type of electromagnetic radiation that can be detected by the eye. It travels as a transverse wave. Unlike a sound waves, light waves do not need a...
