Short Answer

How do sound vibrations of atoms differ from thermal motion?

Heat(thermal motion) creates random movements in atoms whereas sound causes vibration in atoms in a particular direction.

TABLE OF CONTENTS

Step 1:Thermal motion of atoms

When heat is provided to materials, then atoms in that material undergo random motion.

Step 2: Sound vibration of atoms

Sound causes vibrations in atoms in an ordered way.

Sound is more effectively transmitted into a stethoscope by direct contact than through the air, and it is further intensified by being concentrated on the smaller area of the eardrum. It is reasonable to assume that sound is transmitted into a stethoscope \(100\) times as effectively compared with transmission though the air. What, then, is the gain in decibels produced by a stethoscope that has a sound gathering area of\(15.0\;{\rm{c}}{{\rm{m}}^{\rm{2}}}\), and concentrates the sound onto two eardrums with a total area of \(0.900\;{\rm{c}}{{\rm{m}}^{\rm{2}}}\)with an efficiency of\(40.0\% \)?

A diagnostic ultrasound echo is reflected from moving blood and returns with a frequency \({\rm{500 Hz}}\) higher than its original \({\rm{2}}{\rm{.00 MHz}}\). What is the velocity of the blood? (Assume that the frequency of \({\rm{2}}{\rm{.00 MHz}}\) is accurate to seven significant figures and \({\rm{500 Hz}}\) is accurate to three significant figures.)

What is the minimum speed at which a source must travel toward you for you to be able to hear that its frequency is Doppler shifted? That is, what speed produces a shift of \({\rm{0}}{\rm{.300\% }}\)on a day when the speed of sound is\({\rm{331}}\;{\rm{m/s}}\)?

(a) A bat uses ultrasound to find its way among trees. If this bat can detect echoes 1.00ms apart, what minimum distance between objects can it detect? (b) Could this distance explain the difficulty that bats have to find an open door when they accidentally get into a house?

A spectator at a parade receives an \(888\;{\rm{Hz}}\) tone from an oncoming trumpeter who is playing an \(880\;{\rm{Hz}}\) note. At what speed is the musician approaching if the speed of sound is \({\rm{338}}\;{\rm{m/s}}\)?
