A 5W source sends out waves in air at frequency `1000s^(-1)`. Deduce the intensity at a 100 m distance, assuming spherical distribution. If `v=350ms^(-1)` and `p=1.3kgm^(-3)`, deduce the displacement amplitude.

For plane waves in the air of frequency 1000 Hz and the displace amplitude 2xx10^(-8)m , deduc (i) the velocity amplitude, and (ii) the intensity. (Take p= 1.3 kg//m^(3),c=340 m//s)

A point source of power 50pi watts is producing sound waves of frequency 1875Hz . The velocity of sound is 330m//s , atmospheric pressure is 1.0xx10^(5)Nm^(-2) , density of air is (400)/(99pi)kgm^-3 . Then the displacement amplitude at r=sqrt(330) m from the point source is

A source of sound operates at 2.0 kHz, 20 W emitting sound uniformly in all direction. The speed of sound in air is 340 m s^(-1) at a distance of air is 1.2kgm ^(-3) (a) What is the intensity at a distance of 6.0 m from the source ?

A sound wave of frequency 280 Hz has an intensity of 1.00 W//m2 ? What is the amplitude of the air oscillations caused by this wave?

The faintest sound the human ear can detect at a frequency of 1000 Hz correspond to an intensity of about 1.00xx10^-12(W)/(m^2) , which is called threshold of hearing. The loudest sounds the ear can tolerate at this frequency correspond to an intensity of about 1.00(W)/(m^2) , the threshold of pain. Detemine the pressure amplitude and displacement amplitude associated with these two limits. Take speed of sound =342(m)/(s) and density of air =1.20(kg)/(m^3)

The faintest sound the human ear can detect at a frequency of kHz (for which ear is most sensitive) corresponds to an intensity of about 10^(-12)w//m^(2) . Assuming the density of air cong1.5kg//m^(3) and velocity of sound in air cong300m//s , the pressure amplitude and displacement amplitude of the sound will be rspectively ____ N//m^(2) and ____ m .

A 10 W source of sound of frequency 1000 Hz sends out wave in air. The displacment amplitude a distance of 10 m from the source is (speed of sound in air = 340 m/s and density of air = 129 kg/m^(3) )
