Wave Equation Problems

1. Two waves are traveling through the same container of nitrogen gas. Wave A has a
wavelength of 1.5 m. Wave B has a wavelength of 4.5 m. The speed of wave B must be________ the speed of wave A.
a. one-ninth
b. one-third
c. the same as
d. three times larger than

2. As the wavelength of a wave in a uniform medium increases, its frequency will _____.
a. decrease
b. increase
c. remain the same

3. The speed of a wave depends upon (i.e., is causally effected by) ...
a) the properties of the medium through which the wave travels
b) the wavelength of the wave.
c) the frequency of the wave.
d) both the wavelength and the frequency of the wave.

1. The answer is C. The medium is the same for both of these waves ("the same container
of nitrogen gas"). Thus, the speed of the wave will be the same. Alterations in a
property of a wave (such as wavelength) will not ...
