Two sound waves are traveling through a container of unknown gas. Wave A has a wavelength of 1.2 m. Wave B has a wavelength of 3.6 m. The frequency of wave B must be __________ the frequency of wave A.
a. one-ninth
b. one-third
c. the same as
d. three times larger than

the answer is one third but i do not understand why some one please attempt to give some sort of explanation. Thank you!

they both travel with the same speed. So, a longer wavelength means it oscillates more slowly.

Recall that

v = λf

3λ means f/3 to get the same v.

Answer: C

The speed of a wave does not depend upon its wavelength, but rather upon the properties of the medium. The medium has not changed, so neither has the speed.

The answer is C
To know why
U can search it in google !

1.2 × 3 =3.6
So when cancelling 1.2 becomes 1 and 3.6 becomes 3.
