Assume that the sound emission frequency of the bat is 38.5 kHz. During one fast swoop directly toward a flat wall surface, the bat is moving at 0.018 times the speed of sound in air. What frequency does the bat hear reflected off the wall? 040 Number Units the tolerance is +/-8% 086 SHOW HINT GO TUTORTAL 031 LINK TO TEXT LINK TO SAMPLE PROBLEM 039 O5S Question Attempts: 0 of 6 used SAVE FOR LATER SUBMIT ANSWER 040 052 All Rights Reserved.

Explanation / Answer

(340*0.018) = 6.120 m/sec.
Apparent frequency of bleep at the wall = ((340 + 6.12)/340) x 38500 = 39,193Hz.
(39,193 - 38500) = 693Hz.
(38500 + (2 x 693) = 39886 Hz
