A) graph A with slope \[=\frac{{{f}_{0}}}{(\upsilon -{{\upsilon }_{s}})}\]
B) graph A with slope\[=\frac{{{f}_{0}}}{(\upsilon +{{\upsilon }_{s}})}\]
C) graph B with slope \[=\frac{{{f}_{0}}}{(\upsilon -{{\upsilon }_{s}})}\]
D) graph B with slope\[=\frac{{{f}_{0}}}{(\upsilon +{{\upsilon }_{s}})}\]
Correct Answer: A
Solution :
For the given situationfrequency listened by an observer is f. So, \[f={{f}_{0}}\left[ \frac{V+{{V}_{0}}}{V-{{V}_{s}}} \right]\] \[f=\frac{{{f}_{0}}V}{V-{{V}_{s}}}+\frac{{{f}_{0}}}{V-{{V}_{s}}}={{V}_{0}}\] equating the equation \[y=mx+C\] \[m=\frac{{{f}_{0}}}{V-{{V}_{s}}}\]So choice is (A) .You need to login to perform this action.
