Reference no: EM13702821

Solve the all parts of following question:

Question: A car is approaching a reflecting wall. A stationary observer behind the car hears a sound of frequency 790 Hz from the car horn and a sound of frequency 873 Hz from the wall.

Part A: How fast is the car traveling?

.......... km/h

Part B: What is the frequency of the car horn?

........... Hz

Part C: What frequency does the car driver hear reflected from the wall?

............ Hz
