Who is faster sound or light?
The speed of light as it travels through air and space is much faster than that of sound; it travels at 300 million meters per second or 273,400 miles per hour.
Can you make sound travel faster?
Nothing can travel faster than light… except for sound. This is the claim of some US physicists, who say they have designed an unusual waveguide to make sound move at “superluminal” speeds (Appl. Phys.
What happens to time at the speed of light?
Einstein’s theory of special relativity says that time slows down or speeds up depending on how fast you move relative to something else. Approaching the speed of light, a person inside a spaceship would age much slower than his twin at home. Picture a four-dimensional fabric called space-time.
Is sound louder in water?
Sound travels faster in water compared with air because water particles are packed in more densely. Thus, the energy the sound waves carry is transported faster. This should make the sound appear louder.
Why does light have energy but no mass?
Since photons (particles of light) have no mass, they must obey E = pc and therefore get all of their energy from their momentum. But an object with zero energy and zero mass is nothing at all. Therefore, if an object with no mass is to physically exist, it can never be at rest. Such is the case with light.
Why is light affected by gravity if it has no mass?
It might be surprising to you to hear that gravity can affect light even though light has no mass. According to general relativity, gravity is actually caused by a curving of space and time. Since light travels in a straight line through straight spacetime, the curving of spacetime causes light to follow a curved path.
What material has the highest speed of sound?
Does sound travel faster in light?
The speed of sound through air is about 340 meters per second. It’s faster through water, and it’s even faster through steel. Light will travel through a vacuum at 300 million meters per second. No information can propagate faster than the speed of light.
