Question

Two loudspeakers emit sound waves along the x-axis. The sound has maximum intensity when the speakers are 36 cm apart. The sound intensity decreases as the distance between the speakers is increased, reaching zero at a separation of 45 cm .

Part A:

What is the wavelength of the sound?

Express your answer to two significant figures and include the appropriate units

Part B:

If the distance between the speakers continues to increase, at what separation will the sound intensity again be a maximum?

Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

intensity is minimum when path difference=wavelength/2=45

so wavelength=90cm

b)intensity is maximum when path difference=wavelength=90cm
