- Light waves can travel through a much greater distance. Sound waves do not travel far as their energy is dissipated easily.

Aug 13, 2020 · Light travels at \(3.0\times 10^{8}\text{ m/s}\) but sound waves travel at about \(344\text{ m/s}\). What is the time delay for light and sound to arrive from a source that is \(10,000\text{ m}\) away (this can be used to get an approximate distance to a thunderstorm)?

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...
Nov 24, 2023 · Light waves travels at much higher velocity as compared to sound waves. The velocity of light waves through a vacuum is 2.998 x 10 8 m/s. Visible light has a wavelength of range from 400-700nm, Violet light has a wavelength of 400nm whereas red light has a wavelength of 700nm.
By comparison, sound travels just 340 m in one second, about the length of three and a half hockey pitches. The table summarises some similarities and differences between light waves...
- How far does light go? how long does light go. - Jason (age 11) A: Hi Jason, Light just keeps going and going until it bumps into something.
- less than one photon? Can light intensity reduce to a level where it's energy is less than 1 photon (probably after travelling an almost infinite distance from a point source)?
- stars too far away to see? does there is any star that we can can't get it's light because of itis farness?...... sorry with having any problems in my English gramer, my English language is not good enough.
- light going out to space. If we are reflections of light, does that reflection make it out into space and keeps traveling til its asorbed.
Light travels at exactly 299,792,458 meters per second in a vacuum (about 300,000 kilometers per second or just over 1 billion kilometers per hour). As a comparison, sound waves travel at a paltry 343.14 meters per second (about 1,235 kilometers per hour), almost a million times slower than light waves, and the fastest military airplane, the SR ...

As such, nothing can match the 300,000km/s achieved by light travelling through a vacuum – least of all sound, which being waves of compression and expansion in a substance doesn’t even exist in a vacuum. That said, light can be slowed down by being passed through transparent materials – by around 33 per cent in the case of glass.
