MHT CET Physics question
If a particle is travelling with a speed of 0.9 of the speed of sound and is emitting radiations of frequency 1 kHz and moving towards the observer. What is its apparent frequency (in kHz)?
Answer: (D)
Solution
kHz; 1.1, 2.0 and 0.1 kHz are not given by this relation. Hence the correct option is (d).
