Double the speed, double the frequency?

1. Does doubling speed double frequency?
2. What happens to frequency when wave speed is doubled?
3. What happens if frequency is doubled?
4. Does doubling frequency double energy?

Does doubling speed double frequency?

The speed of a wave is unaffected by the change in its frequency. Therefore, doubling the frequency of a wave does not affect the speed of a wave.

What happens to frequency when wave speed is doubled?

doubled. Wave speed equals frequency*wavelength. So doubling the frequency must halve the wavelength in order for wave speed to remain the same.

What happens if frequency is doubled?

Frequency is inversely proportional to the wavelength. Then If the frequency of a wave is doubled, then its wavelength will be half of the original.

Does doubling frequency double energy?

The reason the number of phonons or photons in the second case is cut in half is because this amounts to "upconversion" frequency doubling, in which the energy of two phonons (or photons) is combined to make a new phonon (or photon) having twice the frequency and therefore twice the energy.
