If the frequency of a wave is 100 Hz then the particles of the medium cross the mean position in one second -

In a string wave , all particles of the medium cross the mean position with

In a string wave , all particles of the medium cross the mean position with

In a stationary wave, all particles of the medium cross the mean position with (

In a stationary wave, all particles of the medium cross the mean position with (

The frequency of a wave is 5 Hz. It refers to (type of wave)

Is the frequency of wave changes when it goes from one medium to another medium ?

Find the intensity of sound wave whose frequency is 250 Hz. The displacement amplitude of particles of the medium at this position is 1 xx 10^(-8) m. The density of the medium is 1 kg"/"m^3 , bulk modulus of elasticity of the medium is 400 N"/"m^2 .

When a longitudinal wave propagates through a medium, the particles of the medium execute simple harmonic oscillations about their mean positions. These oscillations of a particle are characterised by an invariant
