A bat flies at a steady speed of 
emitting a sound of 
. It is flying horizontally towards a vertical wall. The frequency of the reflected sound as detected by the bat will be (Take velocity of sound in air as 
).
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Here, bat is a source of sound and the wall is an observer at rest.
Frequency of sound reaching the wall is
where 
is the velocity of sound in air and 
is velocity of source.
On reflection, the wall is the source of sound of frequency 
at rest and bat is an observer approaching the wall
frequency heard by the bat is
