Electrons and Atooms

 

 

Electromagnetic Radiation

 

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

 

 

Wavelength

 

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

 

 

Frequency

 

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

 

 

Amplitude

 

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

;

;

Electomagnetic Spectrum

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

;

;

Quatum

;

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

;

;

Plank’s Constent

 

 

has a value of 6.625×10-34 J.S, where J is the symbol for the joule the SI unit of energy.

 

 

Photoelectic Effects

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

 

 

Photon

 

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

 

 

Atomic Emission Spectrum

 

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