What are waves?
A disturbance that transfers energy from one place to another
100
What does amplitude mean?
The measure of how far the particles in the medium move away from their normal rest position
100
Sound waves are caused by ______________
Vibrations
100
Light waves are disturbances in what?
Electric and magnetic fields
100
What does transparent mean?
matter that transmits light
200
What is a medium?
The material through which a wave travels
200
What is wavelength?
The distance from any point on a wave to an identical point on the next wave
200
Sound cannot travel through what?  
A vacuum such as space!
200
What is the vocabulary term for the transfer of energy as electromagnetic (EM) waves?
radiation
200
What does translucent mean?
Matter that transmits light but does not let the light travel straight through
300
Where would you find the crest on a transverse wave?
The uppermost peak of the wave.
300
What is frequency?
The distance from any point on a wave to an identical point on the next wave
300
How do humans hear sound?
Through their ears- vibrations are converted to electrical signals

What does opaque mean?
Does not let any light pass through
400
How do the particles in a transverse wave move?
Back and forth in the same direction that the wave travels.
400
What two properties of waves affect the amount of energy of the wave?
Amplitude and frequency
400
What is pitch?
How high or low you think a sound is
400
What determines the color of light?
Its wavelength
400
What is a reflection?
The bouncing of light off a surface
500
What is required in a mechanical wave?
A medium for the wave to travel through
500
What type of medium allows sound waves to travel the quickest?
Solids
500
What is loudness?
A measure of how well a sound can be heard
500
What is white light?
All the wavelengths of light in equal proportions

SURPRISE this question is not about light.  If I take a bucket of water and pour it into a super skinny tall glass, tell me what will happen to its mass and volume?
It's mass and volume will stay the same of course!!!  You are just transferring the water into a different shaped container.  Only its shape will change!
