A directional loudspeaker aims a sound wave of Frequency 200 H₂ at wall. At what distance from the wall would you stand and hear no sound at all? (v= 332 m/s).​

The distance from the wall you would stand and hear no sound at all is 0.83 m.

What is speed of wave?

The speed of a wave is the rate of change of distance traveled by a wave with time.

Distance of the wave

The distance at which the wave will have zero amplitude, there will be no sound at all since amplitude of a sound is proportional to intensity of the sound.

The point of zero amplitude, L = λ/₂

Where;

λ is wavelength of the wave

The wavelength of the wave is calculated as follows;

λ = V/f

where;

  • V is speed of sound wave
  • f is frequency of the wave

λ = 332/200

λ = 1.66 m

Distance from the wall a zero sound

L = 1.66/2

L = 0.83 m

Thus, the distance from the wall you would stand and hear no sound at all is 0.83 m.
