A train standing at a certain distance from a railway platform is blowing a whistle of frequency 500 Hz. If the speed of sound is 340 ms-1, the frequency and wavelength of the sound of the whistle heard by a man running towards the engine with a speed of 10 ms-1 respectively are
- 500 Hz, 0.7 m
- 500 Hz, 0.68 m
- 486 Hz, 0.7 m
- 515 Hz, 0.68 m
Answer
(D) 515 Hz, 0.68 m
