Question

If wind blows from a stationary sounding object to a stationary listener, then the apparent frequency n' and actual frequency n are related as :

• A. $n^{\prime }\ge n$
• B. $n^{\prime }<n$
• C. $n^{\prime }=n$
• D. $n^{\prime }>n$

Answer 1

Answer: (C)

$n^{\prime }=n$

Frequency is not affected by blowing of wind long as source and listener are stationary.
