1 Physics and Astronomy Outreach Program at the University of British Columbia Physics and Astronomy Outreach Program at the University of British Columbia Multiple-Choice Questions Animals Bats and the Doppler Shift

2 Physics and Astronomy Outreach Program at the University of British Columbia Physics and Astronomy Outreach Program at the University of British Columbia Question 1 The frequency of sound reflected from the moving object (in the reference frame of the object): Bats and the Doppler Shift A.Is the same as the frequency of sound received by the object. B.Is larger than the frequency of sound received by the object. C.Is smaller than the frequency of sound received by the object. D.Depends on the direction of the velocity of receiving object
