Electromagnetic Radiation

Definition

 

is form of energy that exhibits wavelike behaviors as it travel through the space.

Term

 

 

Wavelength

Definition

 

is the shortest distance between equivalent point on a continous wave.

Term

 

 

Frequency

Definition

 

is the number of waves that pass a given piont per second.

Term

 

 

Amplitude

Definition

 

of a wave is the wave's height from the origin to a crest, ot forn the origin to a trough.

Term

 

 

Electomagnetic Spectrum

Definition
also called the EM spectrum, emcompose all form of electomagnetic radiation with only difference in the type of radiation bring their frequencies and wavelength.
Term

 

 

Quatum

Definition

 

is the minimum amount of energy that can gained or lost by an atom.

Term

 

 

Plank's Constent

 

Definition

 

has a value of 6.625x10-34 J.S, where J is the symbol for the joule the SI unit of energy.

Term

 

 

Photoelectic Effects

Definition
electrons, called photelecton are emitted from metal surface when light of a certain frequency shines on the surface.
Term

 

 

Photon

Definition

 

is a particle of electomagnetic radiation with no mass that cause a quantum of energy.

Term

 

 

Atomic Emission Spectrum

Definition

 

of an element is the set of frequencies of the electomagnetic wave emitted by atoms of the elements.
