It will simply double.
Wavelength = Velocity / Frequency
or in your case
Velocity = Frequency x wavelength

Except that would demand unusual conditions.
'
Doubling of speed can only happen if the wave passes from its first medium to another of very different properties. Any given wave motion has a speed constant for any medium itself that is able to transmit it.
'
For sound, the speed is approximately 340m/s in air, 1500m/s in water (varying very slightly with the density of the air or water). This is irrespective of frequency hence irrespective of wavelength.
'
So for a single medium, as the speed cannot change (ignoring small changes due to density changes) the wavelength is always inversely proportional to frequency only.
The wavelength stays constant.
it doubles
The frequency also doubles of the wave length stays the same. Remember that Velocity = (the wavelength) x (the frequency)
If the frequency remains constant, then the wavelength increases.
The speed changes.
The wavelength stays constant.
it doubles
You actually answered your own question. The wavelength remains the same since it is stated as part of the problem. However, the frequency, which I am betting you are more interested in will double. The frequency is releated to the wavelength and the speed of the wave by the following equation f = v/l where f is the frequency, v is the speed, and l is the wavelength. So if the velocity doubles and the wavelength is constant, then the frequency will double.
The product of (frequency) times (wavelength) is always the same number. (It happens to be the speed of the wave.) So if one of them doubles, the other one gets decreased by half.
The frequency also doubles of the wave length stays the same. Remember that Velocity = (the wavelength) x (the frequency)
If the frequency of a wave is doubled while the wave speed remains constant, the wavelength of the wave will be halved. This is because wavelength and frequency are inversely proportional in a wave, so when one doubles, the other is halved to keep the wave speed constant.
Speed = wavelength x frequency, so wavelength = speed / frequency. Therefore, the wavelength is inversely proportional to the frequency. Double the frequency means half the wavelength.
Halved. The wavelength and frequency of a wave are inversely proportional, meaning that if the frequency doubles, the wavelength is halved in order to maintain a constant wave speed.
Remember that wavelength x frequency = speed of the wave.If you increase the wavelength, the frequency will decrease - since the speed of most waves is more or less independent of the frequency or wavelength.
If the frequency doubles, the wavelength is halved. This is because frequency and wavelength are inversely proportional in a wave. This relationship is described by the formula: frequency x wavelength = speed of the wave.
If the frequency remains constant, then the wavelength increases.
The speed changes.
