A standing wave is established on a string that is fixed at both ends.
If the string is vibrating at its fundamental frequency, how is the length of the string related to the wavelength of the standing wave?

a. The length of the sting is equal to one-quarter of a wavelength.
b. The length of the string is equal to the wavelength.
c. The length of the string is equal to twice the wavelength.
d. The length of the string is equal to one-half of a wavelength.
e. The length of the string is equal to four times the wavelength.
