Does a harmonic wave is travelling along the positive x-axis on a string stretched? Now a new wave is established on the string and it is observed that the wavelength of the new wave is doubled compared to the first wave. What can be said about the frequency of the new wave compared to the first wave?
1) The frequency of the new wave is half of the frequency of the first wave.
2) The frequency of the new wave is the same as the frequency of the first wave.
3) The frequency of the new wave is double the frequency of the first wave.
4) The frequency of the new wave cannot be determined without additional information.
