A wave you see or feel is the result of . . .
the energy that comes from the friction between the wind and the sea
the interaction between a source of energy and a medium
How does energy affect a wave?
The more energy, the bigger and stronger.
What is a wave?
A mechanical wave is . . .
A wave that travels only through matter
What is a medium?
A material in which a wave travels
A type of wave that makes particles move with the motion of the wave
What is a Transverse Wave?
What is a Longitudinal Wave?
What is a Sound Wave
A sound wave is a type of water wave that moves through sponges and travels to the ear to make energy.
What is an Amplitude?
Amplitude is the frequency of a wave with the unit of meters per second.
What is the relationship between wave energy and amplitude?
E = A²
A = E²
E = A³
A = E³
What is Loudness?
How you perceive the energy of a sound wave.
Intensity is . . .
The amount of sound energy that passes through a square meter of space in one second.
What is the Frequency of a Wave?
The number of times the pattern repeats in a given time.
What is Wavelength?
Pitch is . . .
Joni plays a scale on her clarinet. As she plays from low notes to high note, what happens to the sound waves that the clarinet creates?
The amplitude of the sound waves decrease.
The frequency of the sound waves increases.
The intensity of the sound waves increases.
The wavelengths of the sound waves increase.
You are with a friend in the schoolyard. You rest your ear against a metal leg of the swings while your friend gently taps on the leg. You hear tapping. Is it a longitudinal wave or transverse wave.
Longitudinal Wave
Transverse Wave
Both of them
None of them.
What is the Unit that Frequency is measured in?
Watts
Newtons
Volts
Hertz
What is the unit Hz the same as?
1/second
1/meter
1/volt
1/Hz
What is sound measured in?
Recording studios have foam on the walls . . .
How do waves travel through matter?
Through Reflection, Absorption, and Transmission
What is Reflection?
Bouncing of a wave off a surface.
Absorption is . . .
The transfer of energy by a wave to the medium through which it travels.
What is Transmission?
Transmission is the passage of a wave through a medium.
What is Diffraction?
You are in a soundproofed hallway. Someone standing around the corner from you speaks and you hear them. Which laim offers the best evidence and reasoning for this phenomenon.
Sound is not affected by types of materials, because sound can travel through solids, liquids , and gases.
Sound waves are absorbed by the sound-proofed walls and then transmitted through the wall to your ear.
Sound waves diffract so even though the walls do not reflect the sound wave, the sound wave an still travel to your ear.
Sound-proof walls allow sound waves to reflect all of the sound that is directed toward them. So the sound must bounce off them and go to your ear.
The inner ear contains small, fluid-filled chambers called the _.
canal
What does the middle ear do?
Amplifies the sound.
Vibrations from the eardrum transfer to three tiny bones called _.
Hammer
Anvil
Cochlea
Stirrup
