Question 399391
The wavelength, w, in meters per cycle, of a musical note is given by w= r/f
where r is the speed of sound in meters per second and f is the frequency in cycles per second. 
The speed of sound in air is 344 m/sec. What is the wavelength of a note whose frequency in air is 33 cycles per second?
:
Begin by looking at the given formula: w = {{{r/f}}}
:
Look at which of these 3 variable is given:
r = 344 m/sec
f = 33 cps
:
Substitute these in the original formula
w = {{{344/33}}}
w = 10.4 meters is the wavelength

Not that hard, right?
