### What is the wavelength of a sound wave with a frequency of 30 hertz?

That depends on its speed, and therefore on the medium it happens to be in. -- In normal air at sea level, 30 Hz corresponds to a wavelength of about 37.5 feet. -- In copper, 30 Hz corresponds to a wavelength of about 506 feet. -- In diamond, 30 Hz corresponds to a wavelength of about 1,315 feet. -- In water, 30 Hz corresponds to a wavelength of about 160 feet.

### Is there a wavelength for electricity?

Sure, if it is AC (alternating current), you can calculate a wavelength. For example, in copper the speed is roughly 2/3 the speed of light in a vacuum, that is, 200,000 km/sec.; electricity in our homes comes at a frequency of 50 or 60 cycles per second; so (assuming the frequency of 50 cycles), that would give you a wavelength of 200,000 km/sec / 50 Hertz = 4000 km. Sure, if it is AC (alternating…

### What is the distance between two crests of water?

The distance between two crests of water is the "wavelength." Wavelength Is a one complete wave length(wave lenght) That would be the wavelength. wavelength In a wave, the distance from crest to crest is commonly called a wavelength. wavelength The distance between two corresponding crests on any type of wave is called a wavelength. That is what is considered the wavelength. Same thing with the troughs. wavelength The frequency of the wavelenght, or the Hertz…

### If the frequency is doubled then for waves what would be the wavelength and vlocity?

Frequency = Velocity divided by wavelength. So if frequency is doubled that means velocity is doubled but the wavelength is halved. You can see this by keeping wavelength a constant : If Frequency =1 and Wavelength= 1 1= Velocity/1 Velocity=1 If Frequency =2 and Wavelength= 1 2= Velocity/1 Velocity =2 OR keeping Velocity constant: If Frequency =1 and Velocity= 1 1= 1/Wavelength Wavelength =1 If Frequency =2 and Velocity= 1 2= 1/Wavelength Wavelength=1/2
