Question
A car approaching with velocity u towards the stationary observer crosses past him. What is the apparent change in frequency of the note when car is crossing the observer?
Solution
Consider,
v = frequency of note, and
V = velocity of note in air.
The apparent frequency of note while car is approaching before crossing,
The apparent frequency of note after crossing,
The change in the apparent frequency of note on crossing,
v = frequency of note, and
V = velocity of note in air.
The apparent frequency of note while car is approaching before crossing,
The apparent frequency of note after crossing,
The change in the apparent frequency of note on crossing,
