a sound wave passes a point of observation. at this point the time interval between two successive crests is 0.02 seconds which of the following statement about the wave is correct?
a) the wavelength is 50 m
b) the wavelength is 0.02m
c) the frequency is 50 Hz

Time period =0.02s
Frequency is the reciprocal of time period
f=1/0.02=50Hz
Option c is correct
If you wanna find out wavelength then formula should be like this lembda=c/f
c is the speed of light and f is frequency, you can find out by putting values.
Thanks.
