practice quiz properties of sound

the term compression zone describes: a region of high density or pressure in the wave
density, particle motion, temperature and pressure are considered acoustic variables
the average speed of sound in soft tissue is 1.5 4 millimeters per micro second, 1.5 4 meters per millisecond
True orfalse: thickness of the crystal is equal to the first phase true
Which wave provides better image resolution? High Frequency
Which wave provides deeper penetration? Low Frequency
A thinner crystal does what to the wave? Increases the Frequency
Do higher frequency waves travel faster than lower frequency ones? No, They travel at the same speed when in the same medium.
The unit which means cycles per second is the? Hertz
Quartz crystal has the ability to emit an electrical signal when pressure is applied to it. This property is called the? Piezoelectric effect
What is the speed of sound through soft tissue? 1.54 mm/╬╝sec
What is a frequency within the high end of the audible range? 15 kHz
What is a frequency within the ultrasound range? 15 MHz
Ultrasound is a form of? Periodic motion
Which acoustic variable is measured in g/cm3 Density
Which property remains constant as ultrasound propagates through the body? Frequency
Which properties always decrease as ultrasound propagates through the body? Amplitude, Intensity, and Power
How does ultrasound behave when hitting something stiff? Velocity increases
The distance a sound wave travels during one cycle is the? Wavelength
Frequency is inversely related to? Period
What is true of all waves? They carry energy from one site to another
If the frequencies of two waves are identical, what can be said about their periods? Also identical
Three sound waves leave a common location at the same time. One is infrasonic, one is audible and one is ultrasonic. They travel through the same medium towards the same reflector. which would arrive first? All would arrive at the same time
True or False: The frequency of a wave is determined by the medium through which the wave travels. False
The velocity of a sound wave is determined by? Medium
What is the unit for wavelength? Meters/Cycle
What is the Unity for frequency? Hertz
What is the unit for period? Seconds/cycle
What is the unit for Speed? Meters/second
Which frequency of wave has shorter wavelengths? High
What frequency of wave has a longer period? Low

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
