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.
