|---|---|---|---|---|---|
| electromagetic radiation | a from of energy exhibiting wavelike behavior as it travel thorough space; can be described by wavelength, frequency, amplitude, and speed and includes visbile light, mircowaves, xrays, and radio waves
🗑
|
||||
| wavelength | is the shortest distance between equivalent points on a continuous wave
🗑
|
||||
| frequency | is the number of waves given point per second.
🗑
|
||||
| amplitude | of a wave is the waves height from orgin to a crest, or from orgin to a trough
🗑
|
||||
| electromagnetic spectrum | also called the EM spectrum encompasses all forms of electromagnetic radation, with the onl differences in the types of radaton being their fequencies and wavlengths
🗑
|

🗑
|
||||
| photoelectric effect | electrons, called photoelectrons, are emitted from a metal surface when light of a certain frequency shines on the surface.
🗑
