Source and observer both starts moving simultaneously from origin, one along X-axis and the other along Y-axis with speed of source equal to twice the speed of observer. The graph between the apparent frequency (n') observed by observer and time t would be: (n is the frequency of the source)

Text Solution
Verified by ExpertsThe correct answer is:
B
n 1 = 
n tan α = 
const and n 1 remains const and n 1 < n.
tan α = 
n 1 < n
so. graph. must be
