Answer:
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.
