Use the appropriate formulas.
1. f = (wave speed)/(wavelength)
= 3*10^8/400 = ___ Hz
2. Longer audible wavelength
= (300 m/s)/(lower frequency)
= ___ m
Shorter audible wavelength
= (300 m/s)/(maximum frequency)
= ___ m
1.)A radio station transmits waves of length 400m.if the speed of the waves is 3*10power8m/sec,find the frequency of the radio station.
2.)Audible range of frequencies is between 20Hz and 20KHz.Find the range of the wavelengths corresponding to these frequencies.given,velocity of sound=300m/sec
