How can the speed of a wave of sound or light be changed?
The speed of a wave of sound or light can be changed by altering the medium through which it travels. For sound waves, the speed can be changed by changing the temperature, density, or composition of the medium. For light waves, the speed can be changed by changing the refractive index of the medium.
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.
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.
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.
How does the frequency of a sound wave affect the speed at which the sound wave moves?
The frequency of a sound wave does not affect the speed at which the wave moves. The speed of sound in a medium is determined by the properties of that medium, such as its density and elasticity. However, frequency does impact the pitch of the sound we hear.
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.
When a light ray and a sound wave have the same frequency which one has the longer wavelength?
The light wave has the longer wavelength. In the time required for one wiggle, it travels roughly 880,000 times farther than the sound wave does.
What is one way that light differs from sound?
Light is an electromagnetic wave that can travel through a vacuum, while sound is a mechanical wave that requires a medium to propagate, such as air, water, or solids. Light travels much faster than sound, at a speed of approximately 299,792 kilometers per second in a vacuum, whereas sound travels at a much slower speed, around 343 meters per second in air.
Is the speed of a sound wave slower than a electromagnetic wave?
Yes, the speed of sound waves is slower than the speed of electromagnetic waves. Sound waves travel through a medium, such as air or water, at a speed that depends on the properties of that medium. Electromagnetic waves, such as light, can travel through a vacuum at a speed of about 300,000 kilometers per second.
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
What are the three features of a sound wave?
1) Sound wave always require material medium for their propogation. 2)Sound wave are type of transvers wave. 3)Speed of sound wave can be calculated by speed=sqrt(tension*length of wire/massof wire)
