Doppler-Effekt (erweitert)

How to use it

1. Source frequency f₀ = 500 Hz, v_sound = 343 m/s
2. Source velocity vₛ = 25 m/s (toward observer, positive)
3. Observer velocity vₒ = 10 m/s (toward source, positive)
4. Apply formula: 500 × (343 + 10) ÷ (343 - 25) = 500 × 353 ÷ 318

Common mistakes

• ⚠️ Using wrong sign convention for velocities
• ⚠️ Confusing source and observer velocity positions in formula
• ⚠️ Nichtberücksichtigung von direction of motion (toward vs away)

Worked example

Berechnette observed frequency when source moves at 25 m/s toward observer moving at 10 m/s

The observed frequency {f_obs} Hz changes due to relative motion between source and observer
