Calculate new frequency?
A 1MHz ultrasound is emitted 10 meters away from a wall at room temperature. According to the doppler effect, calculate the new frequency when the sound returns to the original place as echo?
Thank you.
1 MHz.
With no velocity differences between the emitter, wall and receiver, there is no Doppler effect.
