• A form of energy that exhibits wavelike
behavior as it travels through space.
• Radio; microwave; infrared; visible light;
ultraviolet; X-rays; gamma rays.
Electrons and the
Electromagnetic Spectrum
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).

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

Electrons and the
Electromagnetic Spectrum
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.
