Fill in the blank: The number of wave cycles per second is called _______
Frequency
Fill in the blank: _______ determines how loud a sound is.
Fill in the blank: Waves can travel through _______, liquids, and solids.
Gasses
Fill in the blank: _______ determines the pitch of a sound.
Frequency
What is the tallest point on a transverse wave?
Crest
Free Response: Describe the difference between a longitudinal and transverse wave.
Transverse waves are waves where the displacement of the medium is perpendicular to the direction of wave propagation, while longitudinal waves are waves where the displacement of the medium is parallel to the direction of wave propagation.
Free Response: Explain how sound waves are different from light waves.
Sound waves are the transmission of sound and light waves are the transmission of light.
Free Response: How does amplitude relate to the energy of a wave?
The higher the amplitude, the more energy in the wave.
Free Response: Why can't sound travel through a vacuum?
Sound requires a medium to travel through (solid, liquid, or a gas) and in space, a vacuum, there is no medium for it to move through.
Free Response: How do frequency and pitch relate?
Frequency of a wave determines the pitch. A high frequency = a high pitch. A low frequency = a low pitch.
What is the lowest point on a transverse wave?
Trough
Multiple Choice: Waves transfer:
A) Only energy
B) Energy and information
C) Only matter
D) Nothing
B) Energy and information
Multiple Choice: Pitch is directly related to:
A) Amplitude
B) Frequency
C) Wave color
D) Wave size
B) Frequency
Multiple Choice: A wave with small amplitude would produce:
A) Very loud sound
B) Quiet sound
C) High pitch
D) Long wavelength
B) Quiet sound
Multiple Choice: The fastest wave transmission occurs through:
A) Gases
B) Liquids
C) Solids
D) Vacuum
C) Solids
Multiple Choice: A high-frequency wave produces:
A) Low pitch
B) High pitch
C) Loud sound
D) Slow movement
B) High pitch
Fill in the blank: The highest point of a wave is called the _______
Crest
Free Response: Describe how changing frequency changes the sound we hear.
A sound with a high frequency would have a high pitched sound (mickey mouse)
A sound with a low frequency would have a low pitched sound (bass drum)
Explain how amplitude changes the energy of a wave.
If the amplitude were to increase then the energy of the wave would increase as well.
Describe how wave speed changes in different mediums.
Explain the relationship between wave frequency and perceived sound.
If you look at a wave that has a high frequency, you would understand that that wave would have a very high pitched sound.
