Q. A source of sound produces waves of wave length 48 cm. This source is moving towards north with speed 1/4 th that of sound. The apparent wavelength of the waves to an observer standing south of the moving source will be

Q. A source of sound produces waves of wavelength 60 cm when it is stationary. If the speed of sound in air is 320 m/s and source moves with speed 20 m/s, the wavelength of sound in the forward direction will be approximately:

The wavelength is 120 cm when the source is stationary. If the source is moving with relative velocity of 60 m/sec towards the observer, then the wavelength of the sound wave reaching to the observer will be (velocity of sound = 330 m/s)

Q. A source of sound is emitting a waves of wavelength 40 cm in air. If this source starts moving towards east with a velocity one-fourth the velocity of sound then the apparent wavelength of sound in a direction opposite to that of source will be

Q. A source of sound produces waves of
