Imagine that you label an air molecule with a radioactive tag and place it 1 millimeter in front of a speaker diaphragm. You play a sine wave through the speaker. Imagine that you are watching the vibration of the basilar membrane at a location that is maximally sensitive to 5,000 Hertz. You play a sine wave that has a frequency of 5,500Hz to the ear. Hz XXX B. 5,500 HZ 4.
Bats use echolocation to locate and identify their prey.
Echolocation is a form of a. active sonar. E. A AND D 7. Immediately after the sound wave reaches the tympanic membrane, acoustic energy is a. converted into neural impulses that travel to the brain. Barn owls can discriminate sounds as being from above or below based primarily on a. difference in the timing of the sound in the two ears. The mathematician Fourier showed that a. any sound can be broken up into sine waves of equal frequency.
