## 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.
