two speakers which are placed 5m apart at one end of a large room are connected to a signal generator which puts out a 2kHz sinusoidal waveform. Calculate the wavelength of the sound.
The second part of this question is:
describe what a person would hear as he moves slowly across the room in front of the speakers and technical name for the interaction process involved.
speed of sound in air 330m/s
v = λf
The Attempt at a Solution
rearranging wave equation to λ= v/f.
I filled in the values for velocity and frequency eg:
λ = 330m/s / 2kHz
which gave me an answer of .165 metres for the original question.
Can someone please advise if I have this correct or am I missing something.
My answer for the second part of the question:
I 'think' the answer would be: a slight shift in frequency due to the "Doppler effect" ?
Thanks for any help.
