Explain the correction given by Laplace for speed of sound wave in air.

Sound waves in air are

Explain propagation of sound waves in air.

Write equation of speed of sound wave in metals.

Write equation of speed of sound wave in ideal gas.

Speed of sound in air at STP is…..

Compared to moisture air speed of sound is greater in dry air.

Explain heart sounds.

Figure 7.88 shows a stretched string of length L and pipes of length L , 2L , L//2 and L//2 in options (a) , (b), (c ) and (d) respectively . The string 's tension is adjusted until the speed of waves on the string equals the speed of sound waves in the air . The fundamental mode of oscillation is the set up on the string . In which pipe will the sound produced by the string cause resonance ?

Explain propagation of sound waves in solids.

Obtain the equation of speed of sound wave in air and give the error in this equations.
