EM Spectrum
Electromagnetic waves travel fastest in this.
What is a vacuum?
State of matter where sound travels fastest.
What is solids?
When light enters an object and doesn't leave
absorption
Highest part of a wave?
What is crest?
As amplitude increases, energy does what
What is increases?
Highest energy waves on the electromagnetic spectrum.
What are gamma rays?
Sound waves, water waves, and earthquake waves are all this type of wave
Mechanical
When a wave hits an object and then bounces back.
What is reflection or reflected?
Distance from one point to next same point.
What is wavelength?
As frequency increases, energy does what
What is increases?
Color if all light waves are absorbed.
What is black?
A wave in which the particles move parallel to the direction the wave is traveling
What is a longitudinal wave?
When a wave goes through this type of material, it can be absorbed or reflected
opaque
Lowest part of a wave.
What is a trough?
As wavelength increases, frequency does what
What is decreases?
Color if all light is relfected.
What is white?
A wave in which the particles travel perpendicular to the direction the waves are traveling
Transverse wave
When a wave changes speeds and direction as it moves from one medium to another.
What is refraction?
The maximum distance that the wave moves from its rest position
What is amplitude?
As wavelength increases, energy does what
What is decreases?
Infrared
Which color of the visible light spectrum has the longest wavelength?
Red
Light passes through this type of material but not completely (it scatters)
What is translucent?
The place a wave starts from
What is rest position?
the number of wavelengths that pass by a point each second
What is frequency?
