Homework Statement
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.
Homework Equations
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.
