This generally happens when a wave moves from one medium into another.
Now, the velocity (v) of a wave (mechanical and electromagnetic) is equal to the product of its frequency (f) and wavelength (λ).
So, v = f x λ
That means if frequency is constant, the wavelength is directly proportional to the velocity.
So, if the speed of the wave increases (while frequency remains the same), the wavelength will also increase.
Whatever the wavelength and frequency happen to be, their product is always equal to the speed.
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).
it would become longer
It will simply double.Wavelength = Velocity / Frequencyor in your caseVelocity = 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.
Nobody invented frequency distribution. Events happen, as is the nature of events. Some events can have different outcomes and a frequency distribution is simply the proportion of times that these different outcomes happen (empirical freq distrib) or are expected to happen based on scientific laws (theoretical freq distrib).
It would change, depending on how much the frequency and the wavelength changes. It varies based on v = fλ.
Increase decrease. The frequency MUST decrease.
As the frequency of a wave increases while the speed remains constant, the wavelength of the wave will decrease. This is because the speed of a wave is the product of its frequency and wavelength, according to the wave equation v = f * λ. So if the speed is constant and frequency increases, wavelength must decrease to maintain this relationship.
That doesn't happen. You're fishing for "frequency increases", because you're unclear on the independent and dependent quantities. Once the wave leaves the source, the frequency doesn't change.
For any electromagnetic wave, from the highest gamma wave to the lowest radiowave, the product of (frequency) times (wavelength) is always the 'speed of light'in whatever substance the waves happen to be waving along at the moment.So if the wavelength of any of them should decrease, for whatever reason, itsfrequency would have to increase, in order to keep the product constant.
Assuming an electromechanical wave not much. The speed of the wave depends on the medium that the wave is passing through. In a vacuum it is the speed of light, through something else a lesser speed. The wavelength stays the same and the frequency stays the same.
If the wavelength is doubled, the frequency of the wave will be halved. This is because the speed of the wave remains constant, so as the wavelength increases, the number of wavelengths passing a point in a given time decreases, resulting in a lower frequency.
When the volume of a wave increases, the amplitude of the wave increases, causing it to become louder. The frequency and wavelength of the wave remain the same. Increasing the volume of a wave does not affect its speed.
Whatever the wavelength and frequency happen to be, their product is always equal to the speed.
If the frequency of a wave is left unchanged, the wavelength will also remain constant. Wavelength and frequency are inversely proportional, so they always adjust together to maintain the speed of the wave.
If the frequency is decreased, the wavelength will increase. This is because the wavelength and frequency of a wave are inversely proportional to each other according to the wave equation λ = c/f, where λ is the wavelength, c is the speed of light, and f is the frequency.
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).
