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.
To double the wavelength of a wave, you need to decrease its frequency by half. Wavelength and frequency are inversely proportional - as wavelength increases, frequency decreases, so doubling the wavelength requires halving the frequency. This change in wavelength can affect the characteristics of the wave, such as its speed and energy.
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.
To double the frequency of a wave, you need to halve either the wavelength or the wave velocity. This is because frequency is inversely proportional to both wavelength and wave velocity. So, if you decrease either the wavelength or the wave velocity by half, the frequency will double.
If wavelength increases, frequency decreases inversely. Wave energy remains the same since it is determined by amplitude and not by wavelength or frequency.
If the frequency of a sound is doubled, the wavelength would be halved. This is because wavelength and frequency have an inverse relationship: as one increases, the other decreases.
Wavelength = 1/frequency. If you double the frequency, the wavelength drops to half.
If the frequency becomes double what it was, then the wavelength becomes 1/2 of what it was.
Speed = wavelength x frequency, so wavelength = speed / frequency. Therefore, the wavelength is inversely proportional to the frequency. Double the frequency means half the wavelength.
As wavelength increases the frequency decreases.

The wavelength is halved.
If the frequency remains constant, then the wavelength increases.
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.

As wavelength goes up, the frequency comes down.
