Best Answer

The frequency also doubles of the wave length stays the same. Remember that Velocity = (the wavelength) x (the frequency)

Wavelength is halved.

Wavelength = 1/frequency. If you double the frequency, the wavelength drops to half.

The wave length would necessarily be one half. The speed would remain the same independent of the frequency.

If the frequency becomes double what it was, then the wavelength becomes 1/2 of what it was.

IF a wave moving at a constant speed were to have it's wavelength doubled (Wavelength x 2), then the frequency of the wave would be half of what it originally was (Frequency / 2).

The speed halves.

If the amplitude of a wave is doubled while the frequency remains constant, the speed of the wave will not change. The speed of a wave is determined by the medium through which it is traveling, not by its amplitude or frequency.

Nothing happens

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.

Wavelength is halved.

When the frequency of a wave is doubled, the wavelength is halved. This is because the speed of a wave is constant in a given medium, so an increase in frequency results in a decrease in wavelength to maintain a constant speed.

speed = freq. X wavelength Hence frequency and wavelength are inversely related when the speed is same. So if the frequency is doubled, then wavelength becomes half of the initial length.

Wavelength = 1/frequency. If you double the frequency, the wavelength drops to half.

The speed halves.

The wave length would necessarily be one half. The speed would remain the same independent of the frequency.

Speed = wavelength x frequency, so wavelength = speed / frequency. Therefore, the wavelength is inversely proportional to the frequency. Double the frequency means half the wavelength.

If the frequency becomes double what it was, then the wavelength becomes 1/2 of what it was.
