A siren emitting wavefronts of 1000Hz and moving with a velocity of +2.00m/s along the pos x-axis, approaches a reflecting wall. At the same time a listener is running with a velocity of -10m/s along the negative x-axis away front eh source of the wall. Assume the speed of sound in the air is 340m.s. Find beat frequency that could be heard by the runner. answer = feat = in between 10 and 15hz

An ambulance is moving with a velocity of 45.0 m/s. The siren has a frequency of 130 Hz. The temperature of the air outside is 90° F a) What frequencies are observed by a stationary person on the sidewalk as the ambulance approaches and after it passes? b) The ambulance now stops and you run towards it at 4.0 m/s along the sidewalk. What is the frequency you observe? c) The sound intensity level of the siren is 110 dB....
I am completing a study guide for the next section of class
because I am trying to get ahead. Any suggestions?
