A sound generator produces 25 waves every 0.1 seconds. If the speed of sound is 330m/s find
a) wavelength of the sound
b) the period of the waves
Ok, for a I got 1.32m.
Wavelength=V/F =330/250 (I got this by using 25/0.1) giving me 1.32m
b) I got stuck with the period.
I thought I could work backwards.....
Period (T) =1/F
F= V/Wavelength
F=330/1.32=250
1/250= 4x10^-3 (0.004) 0.004 seconds
Is this right?
