According to Einstein's Special Relativity, the speed of light has a unique status: it's a fundamental feature of our Universe, representing the maximum speed at which information can travel from place to place. As such, nothing can match the 300,000km/s achieved by light travelling through a vacuum – least of all sound, which being waves of ...

The first notable difference between the speed of sound and light is how fast they are. In Earth’s atmosphere, the speed of sound averages at about 761-miles per hour (1,225-kilometres per hour). That may seem fast, yet when compared to the speed of light, it seems quite small. Light travels at a staggering 670-million miles per hour (1.07-billion ...
In order for sound to exist, it must have a medium to travel through. For sound, this medium is air, and that’s why sound does not exist in the emptiness of space. Meanwhile, light does not need a medium to exist. Rather, light travels independently of any medium, and thus it can travel through space, unlike sound.
Another notable difference between light and sound is that the speed of light is constantwhile the speed of sound is not. Since the speed of sound requires air to exist, its speed is dependent upon the density and temperature of air. For example, when we say that sound travels at 761-miles per hour, this is only the case at sea level and when tempe...
The speed of sound is fast, yet it is by no means the fastest thing in the universe. It is not even the fastest thing on Earth. Human’s have broken the sound barrier countless times, a speed known as supersonic speed. Light is a different story, however. The speed of light is a fixed law of nature, and it represents the fastest possible speed anyth...
Dec 29, 2006 · The speed of sounds is approx. 300 m/s (1000 ft/s), while the speed of light is 300,000 km/s (approx.190,000 miles/s). Therefore, the sound arrives about 1/3 of a second after the corresponding movement, i.e. starts to be recognizable. In a theater the time difference is too short to be recognized. The most striking experience of the different ...
Apr 26, 2018 · The exsit of medium will then reduce the travel of light, the water reduce stronger than air. Sound is produced by the vibration of matter, it travels by the matter interact with each other. So it depend on the medium, the density of water are larger than air, then the interaction between the water molecule are larger than air molecule.
Solution. Light and sound are very different. Sound is actually a mechanical disturbance through air or another medium. Sound always needs a medium to travel through and the type of medium determines its speed. Imagine a bunch of molecules bouncing around in the air. If you hit an object or make a fast motion, the molecules that you push are ...
Feb 3, 2024 · What is the main difference between light and sound? – Sound is only a wave, whereas light exhibits both wave and particle properties. – Sound is a longitudinal wave, but light is a transverse wave. – Sound needs a material medium to travel, light can propagate through vacuum also. – Light travels much faster than the sound.
Sep 27, 2015 · Light, on the other hand, is not a pressure wave—it’s a fundamental particle. One ray of light is typically called a photon, and it’s an electromagnetic disturbance. Light doesn’t need a medium to travel. The speed of sound through air is about 340 meters per second. It’s faster through water and it’s even faster through steel.
