Explain how sound is actually a form of energy. In what medium do sound waves travel? 1-2 paragraphs

Expert Solution

Sound is the movement of energy through substances in longitudinal(compression / rarefaction)waves.

In our atmosphere there are lots of air molecules while we make a noise or while we play a song the air molecule vibrates and releases a energy called sound.

Sound is considered as a form of energy because:

It obeys the first law of thermodynamics which states that energy can neither be created nor be destroyed but it changes from one form to another.
It is considered as a mechanical energy which has both potential as well as kinetic energy.
Sound is produced when a force causes an object or substance to vibrate- the energy is transferred through the substance in a wave.
Example:A vibrating drum in a disco transfers the sound energy to the room as sound. Kinetic energy from the moving air molecule transfers the sound energy to the dancers eardrums. Notice that kinetic energy(movement)energy in the sticks is being transferred into sound energy

Sound vibrations create sound waves which move through mediums such as air and water before reaching our ears.

A tuning fork generates sound waves with a frequency of 230 Hz. The waves travel in opposite directions along a hallway, are reflected by walls, and return. The hallway is46.0 m long and the tuning fork is located 14.0 m from one end. What is the phase difference between the reflected waves when they meet at the tuning fork? The speed of sound in air is 343 m/s. (Ans in degrees)

1. How do tuning forks produce sound waves? Explain. 2. What physical aspect of the fork determines the wavelength? 3. Where are the nodes on a tuning forks? 4. Why does the sound produced depend heavily on the orientation of the fork? This is referred to as 'Directionally Dependent.' 5. How should you orientate the fork in order to best hear the sound it produces?

Waves travel at different velocity in different medium. How does wave velocity effect wave frequency?

For this problem, assume that high frequency sound waves travel through human tissue at 1500 m/s (about the speed of sound in water). a) Measurements of the blood flow in the ascending aorta shows a maximum speed of 92.00 cm/sec. Assuming the ultrasound frequency used is 2.000000 MHz (the paper uses 2.25 MHz), calculate the frequency as seen by the blood that is traveling toward the ultrasound transducer at 92.00 cm/s. The transducer, which both transmits and receives the sound...
