Doppler — Observer Moving — Previous-Year Questions
5 previous-year questions on Doppler — Observer Moving, drawn from JEE Mains, JEE Advanced, NEET UG, and CUET papers. Every question carries a worked-out explanation.
Q1. Observer approaches stationary 500 Hz source at 40 m/s. v_sound = 340 m/s. f':
JEE 2022Q2. If observer RECEDES at 40 m/s instead:
JEE 2021Q3. Doppler effect formula for moving observer vs moving source:
JEE 2020Q4. Both source and observer move TOWARD each other at v_s = v_o = 20 m/s. v = 340 m/s, f = 1000 Hz. f':
JEE 2019Q5. If both source and observer move with the SAME velocity (e.g., car following another), Doppler shift is:
