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
absorbtion
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?
How is an echo created?
Sound reflecting off a surface back to the listener
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?
What shape are sounds waves?
Longitudinal or compression
Corresponds with a high frequency.
What is high energy or short wavelength?
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?
The main category that sound waves are in.
What is a mechanical wave?
When a wave changes speeds and direction as it moves from one medium to another.
What is refraction?
Maximum distance particles move in a wave
What is amplitude?
As wavelength increases, energy does what
What is decreases?
Causes us to see the color of things.
What is reflection?
Name 3 examples of mechanical waves
sound, ocean, seismic
This device splits white light into a "rainbow" of individual wavelengths
a prism
When particles in a longitudinal (compressional) wave are spaced far apart
rarefaction
Relationship where one thing increases as the other thing decreases.
What is inverse or indirect?
