the wave length will increase
The wavelength decreased and the frequency increased.
In this case, the wavelength increases. The wavelength, multiplied by the frequency, is equal to the speed of the wave - and in most types of waves, the speed is more or less independent of the frequency.
If the frequency stays the same, then the wavelength stays the same.
When wavelength decreases, frequency increases, and when wavelength increases, frequency decreases. The product of (wavelength) times (frequency) is always the same number ... the speed of the wave. So when one of them changes, the other one must change in the opposite direction in order for their product to remain unchanged.
The wavelength would double.
The wavelength decreased and the frequency increased.
In this case, the wavelength increases. The wavelength, multiplied by the frequency, is equal to the speed of the wave - and in most types of waves, the speed is more or less independent of the frequency.
The freequency of a wave is increased when the wavelength is decreased. This is because the product of the frequency and the wavelength are a constant that determines the speed of the wave c=fw.
If you are talking about an electromagnetic wave; energy is proportional to frequency (E=hf), and frequency is inversely proportional to wavelength (wavelength equals velocity divided by frequency). So when the wavelength is increased, the energy is decreased.
If the frequency stays the same, then the wavelength stays the same.
When wavelength decreases, frequency increases, and when wavelength increases, frequency decreases. The product of (wavelength) times (frequency) is always the same number ... the speed of the wave. So when one of them changes, the other one must change in the opposite direction in order for their product to remain unchanged.
The wavelength would double.
As wavelength decreases, energy increases, because the two are inversely related. Conversely, as wavelength decreases, frequency increases.
Whatever the wavelength and frequency happen to be, their product is always equal to the speed.
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.
It would change, depending on how much the frequency and the wavelength changes. It varies based on v = fλ.
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).
