A) \[{{n}_{p}}={{n}_{R}}=nQ\]
B) The rate of change in beat frequency is minimum when the car passes through Q
C) The plot below represents schematically the variation of beat frequency with time
D) The plot below represents schematically the variation of beat frequency with time
Correct Answer: C
Solution :
According to Doppler?s effect Apparent frequency \[n'=n\left( \frac{v+{{v}_{0}}}{v+{{v}_{s}}} \right)=1392\left( \frac{343+10}{343+5} \right)\] \[=1412 Hz\]You need to login to perform this action.
