Sound waves of frequency $600 Hz$ fall normally on a perfectly reflecting wall. The shortest distance from the wall at which all particles will have maximum amplitude of vibration is (speed of sound $= 300 ms^{- 1}$ )

Options:

Answer:

Solution:

The maximum displacement of the wave will occur at antinode of the wave. The first antinode will be a point where, $d = \frac{λ}{4}$ The wavelength is given by, $λ = \frac{v}{f} = \frac{300}{600}$ So, $d = \frac{0.5}{4} = \frac{1}{8} m$
