Homework Statement
A room is 4m wide in the x direction, ignore the y and z directions. Compute the longest sound wave that can occur in the room and its frequency.
Homework Equations
speed of sound = 350 m/s
λ = speed/frequency
The Attempt at a Solution
Since the room is 4m wide and sound is a stationary wave, the longest wavelength that can occur is 4m.
λ = 4m
frequency = speed/λ = 350/4 = 87.5 Hz
This just seems incredibly simple, is there anything I'm missing?
