A whistle giving out a sound of frequency 450Hz , approaches a station – InterviewSolution

1.	A whistle giving out a sound of frequency 450Hz , approaches a stationary observer at a speed of 33ms_(1). The frequency heard by the observer is (speed of sound =330m s_(1)____.
Answer» Solution :APPARENT frequency `n.=((v)/(v-v_(s)))n` `=((330)/(330-33))xx450=1.11xx450` n.=500Hz Data: `v=330ms^(-1)` `v_(s)=33ms^(-1)` n=450Hz n.=?
