Explanation:
The frequency and the wavelength of a wave are related by the equation

where
v is the speed
f is the frequency
is the wavelength
For the sound wave in this problem, we have
f = 634 Hz (frequency)
(wavelength)
Therefore, the speed of the wave is

The speed of sound in air depends on the temperature according to the equation

where T is the temperature.
In this problem, we know the speed, so we can calculate the temperature:
