Many factors affect the speed of a wave of sound or light, but the easiest factor to change is the medium through which the wave travels.

The speed of sound, 332 meters per second in dry air at sea level at 0oC, increases with temperature. It is much higher in liquids, about five times faster than in gases, and in metals it travels ten to fifteen times as fast as in air. It travels faster through gases less dense than air such as hydrogen and helium, but slower in heavier gases such as carbon dioxide. Sound does not travel through a vacuum because it relies on the vibration of atoms. It is also affected by humidity in air and the specific heat, density, and elasticity of any other medium through which it travels.

The speed of light, about 300,000 kilometers per second in a vacuum, is less when it travels through any other medium. While it is very slightly slower in air, it travels at anywhere between 3/4 to less than1/2 as fast through liquids, glass and crystals, depending on the refractive index of the material.

How can the speed of a wave of sound or light be changed?

Actually it cant be changed unless you move it for the light and the sound is like in echos get it.


Is wavelength of sound greater than light?

no,wave length of sound is equal to wavelength of sound as when thunder appears,light appears first than sound because of more speed than sound but we can't considere that wave length of sound is greater than that of light


The speed of a wave is its wavelength multiplied by its what?

The speed of light is fairly constant. 3.0X10^8 meters per second. Sounds' speed varies with conditions , but like light it is not changed by wavelength/frequency or amplitude.


What is the wave in which amplitude changes to create sound?

The wave in which amplitude changes to create sound is a sound wave. The intensity of the wave will be changed by energy.


Are sound waves light waves?

No, sound waves are not light waves. The two are completely different.Sound waves are longitudinal mechanical waves, while light waves are transverse electromagnetic waves, and sound requires a medium through which to travel, but light does not.A brief outline of key differences between light waves and sound waves:Sound requires a medium (gas, liquid, air) to travel through. Light does not.Light can also be treated as a particle, sound cannot.How you calculate the energy of a sound, or light wave is also different. Light energy is related to the frequency (or wavelength, these two values are closely related) - "E=hf". The energy of a sound wave is related to it's amplitude (|a|2)and frequency.The speed of sound is relative to the speed of the observer, while the speed of light is constant, regardless of the speed of the observer.Sound is a pressure wave, a region of higher and lower densities in a material, moving through the material. Light is an oscillation in the strength of electrical and magnetic fields moving through space.They are different types of waves, sound is a compression or longitudinal wave, light is a transverse wave.

Is the speed of sound equal to an electromagnetic wave?

No, speed of sound in air is much slower than the speed of light in vacuum.


Is it correct to say that in every case any radio wave travels faster than any sound wave?

Yes. Radio is a form of electromagnetic wave, so it travels at the speed of light. Since sound requires a physical medium and it is (theoretically) impossible for matter to attain the speed of light, the speed of sound can never be equal to/above the speed of light, and this statement is correct.

Which property of a sound wave is changing when the air is removed?

Well, the six properties that describe any wave, including sound waves, are its phase, amplitude, frequency, wavelength, speed, and direction of propagation. I'm not sure if by "air is removed" you mean the wave is now in a vacuum or if you mean it has transferred to another medium. If you mean that it's now in a vacuum, all properties of a sound wave have changed, specifically they've changed to 0 since sound can't travel in a vacuum. If you mean that it's now in another medium, the sound wave's speed and direction have changed.


Does a radio wave travel faster than a sound wave?

Radio waves are sound. Therefore, yes, by definition, they travel at the speed of sound.


What is the wave in which amplitude changes to create sound?

The wave in which amplitude changes to create sound is a sound wave. The intensity of the wave will be changed by energy.

How does the frequency of a sound wave affect the speed at which the sound wave moves?

Frequency and speed of propagation of the wave are independent of one another. The medium determines the speed of propagation.


What do we see that the amplitude of a wave produces?

The amplitude of a wave produces the intensity of the wave. With a light wave, it is the intensity of the light, with a sound wave, it is how loud the sound is
