WJHS - Electromagnetic Spectrum
|Transverse Wave|| |
Particles move up and down as the wave moves forward
1,000,000,000,000 Hz = The range of frequencies of visible light
|1 Meter|| |
1,000,000,000 nanometers (nm) = the range of wavelengths of visible light
Refers to the number of complete cycles, crest to crest,or trough to trough that occur per second. Units are the Hertz = Hz
Waves are labeled with positive and negative motion. The _________ is the extreme on the positive (+) side.
|The Electromagnetic Spectrum|| |
A group of energy forms including radio waves, microwaves, and gamma rays.
|Sir Isaac Newton|| |
Conducted the first experiments using prisms to prove that white light is made of colors.
This is the distance from "rest" to "crest"
Waves are labeled with positive and negative motion. The _______ is the extreme on the negative (-) side.
When a light wave meets a boundary it can be bounced off a surface.
Caused by a disturbance that transfers energy from one point to another.
|Longitudinal Wave|| |
Particles move back and forth (oscillate) like a slinky.
Occurs when a wave crosses a boundary from one medium to another causing the speed of light to change.
The distance from crest to crest or trough to trough.
A device that works by agitating, then organizing, then energizing particles enough that they stay as a very tight beam of one frequency = one color
|Diffraction Grating|| |
The plastic material in the eyepiece of a spectroscope covered with very close, straight lines.
|Kinetic Energy|| |
Radiant energy is an example of this type of energy
A device that uses diffraction to view the spectrum colors of light.
|ROY G BIV|| |
Colors of the visible spectrum
|Radiant Energy|| |
A form of kinetic energy that can travel through the vacuum of space.
