A bat flying at 5.00 m/s is chasing an insect flying in the same direction. The bat emits a 40.0 kHz chirp and receives back an echo at 40.4 kHz. Assume the speed of sound is 343 m/s. 1. What is the equation for doppler shift? 2. If you were calculating the frequency of the chirp observed by the insect, what would the value of fs be? 3. For question 2, would vo represent the velocity of the bat or the insect? Does the motion of the insect increase or decrease the frequency observed by the insect? Would vo be positive or negative? 4. For question 2, would vs represent the velocity of the bat or the insect? Would vs be positive or negative? 5. Write the doppler shift equation to find the frequency of the chirp observed by the insect. Use fi for the frequency observed by the insect and vi for the velocity of the insect.
