A cyclist is using a loudspeaker to measure her speed. She cycles
directly towards the loudspeaker which emits a sound with a constant
frequency 261 Hz. The cyclist measures the frequency to be 269 Hz.
You should assume that the speed of sound in air is 335 m s-¹.
(a) Calculate the speed of the cyclist.
(b) Describe briefly what the cyclist will hear as she passes the
loudspeaker.
Wei is standing on a platform when an approaching XPT train sounds its horn. The frequency of the horn is 500Hz and the train is travelling at 126km h- 1. What is the frequency of the horn as heard by Wei? (Assume the speed of sound in air is 340ms- 1.)
The equation of a sound wave in air is given by
p - (001 N/m ) sin[(1000 s )t- (30 m)x)
(a) Find the frequency, wavelength and the speed of
sound wave in air. (b) If the equilibrium pressure of air
is 1.0 x 10° N/m?, what are the maximum and minimum
pressures at a point as the wave passes through that
point?
