Doppler Effect

Given, air pressure,

p_%7Bo%7D%3D10135%5C%2Cp_%7Ba%7D

and pressure at the centre of rarefaction,

p_%7B1%7D%3D91000%5C%2Cpa

As we know that, during the propagation of sound wave in air pressure varies as

Thus, we have

p_%7B1%7D%3Dp_%7B0%7D-dp

91000%3D101325-dp

(putting values)

%5Ctherefore%20dp%3D101325-91000

%3D10325%5C%2Cpa

Thus, the pressure at the centre of compression

p_%7B1%7D%3Dp_%7B0%7D%2Bdp

%3D101325%2B10325

%3D111650%5C%2CPa

Therefore, the most appropriate option is (c)
