A source moves towards a stationary observer with a speed of 10m/s. If the frequency of the source is 10Hz what will be the wavelength of sound heard by the observer? Speed of sound = 330m/s.(a) 32m(b) 34m(c) 33m(d) 31m
Correct answer is (a) 32mFor explanation: Apparent frequency F = f(330+v0)/(330+v8)= 10(330)/(330-10) = 10.31Hz.Wavelength = 330/F= 330/10.31= 32.007m = 32m.
