A police car emits a siren at a frequency of 900 Hz. If the car is moving toward you at 60 m/s while the sound speed is 340 m/s, what frequency do you perceive?
💡 Hint: Calculate using the Doppler formula carefully.
If a source emitting sound at a frequency of 400 Hz is moving away from you at 40 m/s, what will be the observed frequency? Use sound speed of 340 m/s.
💡 Hint: Remember to plug the values into the formula correctly.
