The point of destructive interference occurs when the result is within an integer value of +0.5.
distance between the speakers, d = 2.0 m,
frequency, f = 1800 Hz,
speed of the sound, v = 340 m/s,
and distance below the speakers, c = 4 m.
L= [tex]\sqrt{4 + 16}[/tex]
L= 4.47 m.
The wavelength of the sound wave is by:
Wavelength (λ)= V /F.
λ=340/1800
λ= .188 m
constructive interference, perfect destructive interference are
x= (4.7-4)/.188
x= 2.5
The higher frequency and the higher pitch are produced by sounds with shorter the wavelengths. So, long waves the sound are low and short waves sound is high.
