• A form of energy that exhibits wavelike behavior as it travels through space.

• Radio; microwave; infrared; visible light; ultraviolet; X-rays; gamma rays.


Wave Properties — wavelength (shortest distance between equivalent points on a wave form); frequency (number of waves that pass a given point per second); speed (wavelength X frequency).

wavelength.htm


Electromagnetic Spectrum — all forms of EM radiation; the only difference is frequency and wavelength. ALL speed of light (3.00 x 108 m/s).

Process — electricity is passed through a tube filled with neon gas; the electrons in neon atoms absorb the energy and move in their electron clouds into an excited state; they then lose energy, release it as light, and return to a ground state.



Atomic Emission Spectrum — unique set of EM waves emitted electrons of atoms of each element.
