AP EAMCET · PHYSICS · Waves and Sound
A small source of sound vibrating at a frequency is rotated along a circle of radius at a constant angular speed of revolutions per second. The minimum and maximum frequency of the sound observed by a listener situated in the plane of the circle is (Speed of sound is )
- A
- B
- C
- D
Answer & Solution
Correct Answer
(D)
Step-by-step Solution
Detailed explanation
In one case the source is moving away and in one case this is moving towards while the observer is in rest so using Doppler shift in sound, f=f0vv±vs, here the angular velocity is given, ω=5 rev s-1 and the radius of the circle is, 1π m so the…
