Two vehicles, each moving with speed u on the same horizontal straight road, are approaching each other. Wind blows along the road with velocity $w$. One of these vehicles blows a whistle of frequency $f_1$. An observer in the other vehicle hears the frequency of the whistle to be $f_2$. The speed of sound in still air is V. The correct statement(s) is (are) :
Select ALL correct options:
A
If the wind blows from the observer to the source, $f_2>f_1$.
B
If the wind blows from the source to the observer, $f_2>f_1$.
C
If the wind blows from the observer to the source, $\mathrm{f}_2<\mathrm{f}_1$.
D
If the wind blows from the source to the observer,$\mathrm{f}_2<\mathrm{f}_1$.
