Two loudspeakers emit sound waves along the x-axis. The sound has maximum intensity when the speakers are 19 cm apart. The sound intensity decreases as the distance between the speakers is increased, reaching zero at a separation of 52 cm .
Required:
Part A) What is the wavelength of the sound?Part B) If the distance between the speakers continues to increase, at what separation will the sound intensity again be a maximum?

The wave length of the sound is 66 cm.

The separation between the speakers is 85 cm.

Explanation:

Given that,

Distance between the speakers = 19 cm

Reaching zero at separation  = 52 cm

(a). We need to calculate the wave length of the sound

Using formula of wavelength

Put the value into the formula

The wave length of the sound is 66 cm.

(b). if the distance between the speakers continues to increase the intensity will again be a maximum when the separation between the speakers that produces a maximum has increased by one wave length

We need to calculate the separation between the speakers

Using formula of separation

The separation between the speakers is 85 cm.

Hence, The wave length of the sound is 66 cm.

The separation between the speakers is 85 cm.

the answer is to check all of them! they all apply well at least i think so!

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000
