Sarah hears a sound that is slowly gets higher and higher in pitch. What would not change in this sound wave?
A. Wavelength
B. Frequency
C. Amplitude
D. All of the above would change
C. Amplitude
200
What is happening to the wave that is labeled A and B?
A- Reflected
B- Absorbed
300
What do we call this type of wave?
Transverse- particles travel perpendicular (up and down) to the direct the wave travels.
300
What unit of measurement is used to measurement the loudness of sound.
Decibels (dB)
300
Density is how much matter is packed into a space. The more dense something is, the faster sound travels through it. Which of these is the LEAST dense?
solid liquid gas
gas
300
As the area increases outward from the horn of the trumpet, what happens to the intensity the a sound wave the farther away you get?
The intensity/sound decreases
300
What are the three small bones in our inner ear?
hammer (malleus), anvil (incus), and stirrup (stapes)
400
What happens to the wavelength of a transverse wave as the frequency increases?
The wavelength decreases
400
Explain the relationship between wavelength and frequency.
If the wavelength increases, the frequency decreases.
If the wavelength decreases, the frequency increases.
400
Look at column A and column B. Which column would show what sound cancelling headphones do?
B- Destructive Interference (the sound waves cancel each other out)
400
How would the pitch of the police siren sound different at point A compared to point B?
Point A would have a lower pitch and point B would have a higher pitch.
400
This type of wave has a frequency that is higher than what a human can hear, and may be used to detect pregnancy or identify a medical problem.
Ultrasound
500
What does a wave carry from one point to another?
energy
500
If you increase the SPEED of a wave, you also increase the _____________.
frequency
500
Why do we see lightning before we hear thunder?
Light moves faster than sound.
500
In which medium (A, B, or C) would sound travel fastest through and why?
Medium A because it is the most dense medium (particles are closest together so there are more collisions when the wave is vibrating).
500
This is used by some animals, such as dolphins, to locate an object by means of reflected sounds?
echolocation
