Wave Properties
Can be measured as the distance between two adjacent crests of a transverse wave or two adjacent compressions of a longitudinal wave
What is Wavelength?
Your perception of the energy of the sound
What is Loudness or Volume?
Portion of electromagnetic spectrum that is visible to the human eye; made of colors
What is Visible Light?
Point inside the Earth where an earthquake begins.
What is Focus?
The pinna, ear canal, and ear drum make up the outer ear
What is the Outer Ear?
Materials(matter) through which a wave travel
What is a medium?
The perceived frequency of sound
What is Pitch?
An object that allows a few light waves to pass through. You can almost see through these objects.
What is Translucent?
Point on Earth’s surface above focus.
What is Epicenter?
Controls that amount of light entering the eye
What is the Iris?
The maximum distance the particles of a medium move from their resting position
What is Amplitude?
Used to measure the frequency of sound (pitch)
What is Hertz?
When light waves hit atoms of a medium and cause them to vibrate. The more vibration the hotter the object becomes. The object will emit the heat as thermal energy.
What is absorb?
A wave of energy that travels through the Earth, away from an earthquake in all directions.
What is Seismic Waves?
Converts light to electric signals, contains cells called rods and cones
What is the Retina?
The number of waves that pass a fixed point in a given amount of time; measured in hertz (Hz)
What is Frequency?
Used to measure the amplitude of sound (loudness or volume)
What is Decibels?
An object that does not allow light waves to pass through it – you CANNOT see through it
What is opaque?
A type of seismic wave that compresses and expands the ground (like an accordion).
What is a P wave?
Has the smallest bones in the body: the hammer, anvil and stirrup
What is the Middle Ear?
The lowest point and the highest point of a transverse wave
What are Crest and Trough?
Vibrations that travel through air or another medium and can be heard when they reach a person’s or animal’s ear
What is Sound?
When light waves bend.
What is Refraction?
Instruments located at or near the surface of the Earth that record seismic waves.
What are Seismographs?
Allows us to see objects far or near.
What are the lens?
