Multiple Choice: A small amplitude transverse wave is travelling on a string. The frequency of the wave is suddenly doubled. Which one of the following is a true statement?
a) The period of the wave doubles
b) The wavelength doubles
c) The speed of the wave doubles
d) The wavelength is cut in half
e) The speed of the wave is cut in half



Answer :

The wavelength of the string is cut in half. The answer is D. The higher the frequency the shorter the wavelength. They are inversely proportional.
