Sound Terms
Waves which oscillate (move the medium up & down) in the direction which is parallel to the direction in which the wave travels.
Longitudinal Waves
When light bounces off a surface?
Reflection
A disturbance that transfers energy from place to place.
Wave
186,000 miles/second
Known as the unit for measuring Frequency.
Hertz
The Sound of Music
When sound waves bounce back to you.
Echo
When a light ray hits an object and bends.
Refraction
The substance or material through which a wave travels.
Medium
Describe the pathway that light travels.
Straight Line
When an object (ex. pencil) appears bent when sticking out of water, what is happening to the light?
It is changing speed or changing direction.
Light 'Em Up
Maximum distance that the particles of the medium move away from the rest position.
Amplitude
The process where an object converts the energy of light into another form of energy.
Absorption
Waves that move the medium at right angles to the direction in which the waves travel.
Transverse Waves
This light wave characteristic determines the color and energy of light?
Wavelength
An object that can split white light into a rainbow.
Prism
Good Vibrations
The high point or high part of a transverse wave.
Crest
When light passes through a medium.
Transmission
It is a repeated up and down or back and forth motion.
Vibration
The portion of the electromagnetic spectrum that is visible to human eyes.
Visible Light

Name the 1970s band https://youtube.com/clip/Ugkxiga_ttVKwyktizcSIDUlGd95hvOCP63V?si=BQHk-9KMUwqrTUyn
Electric Light Orchestra (ELO)
The number of complete waves that pass a given point in a certain amount of time.
Frequency
The dark area or shape produced by a body coming between rays of light and a surface.
Shadow
The SHORTER the wavelengths, the ____________ the sound.
Why do we see lightning before we hear the thunder?
Because light travels faster than sound.
What happens to the volume when a sound wave's amplitude is increased?
The volume gets louder.
Blinded by the Light
The kind of waves that require a medium through which to travel.
Mechanical Waves
What do we call light particles which are packets of energy?
Photons
What is something that light waves can do that sound waves cannot do?
Travel through the emptiness of space (vacuum)
An object appears green. Why?
All other colors are absorbed by the object except green which is reflected by the object.
The kind of waves that DO NOT require a medium through which to travel.
Electromagnetic Waves
