Visible Light
THESE ARE MEASURES OF LENGTH.
THEREFORE, THE COLOR OF THE LIGHT MUST
BE RELATED TO THE WAVE’S ___________.
Visible Light
THESE ARE MEASURES OF LENGTH.
THEREFORE, THE COLOR OF THE LIGHT MUST
BE RELATED TO THE WAVE’S LENGTH.
Visible Light
THE WAVELENGTH DICTATES WHAT COLOR
THE VISIBLE LIGHT IS.
THE FREQUENCY DICTATES THE AMOUNT OF
ENERGY THE LIGHT HAS.
Visible Light
THE PHOTONS IN VIOLET LIGHT (400 NM)
ARE HIGHER IN ENERGY THAN THE PHOTONS
IN RED LIGHT (700 NM).
WHAT ABOUT THE LIGHT THAT
IS NOT FROM THE SUN?
WHAT ABOUT LIGHT FROM FIRE?
IF WE LIGHT AN ATOM ON FIRE
WILL THE ELECTRON DO A OR B?
When a substance is
heated in a flame, it’s
electrons absorbs the
energy from the flame.
This absorbed energy
pushes the electron
into excited energy
levels.
Excited Electrons
eventually
transitions back
down to the
ground state.
When an electron
transitions from
a higher energy
level to a lower
energy level a
photon of light is
emitted.
Which color
has the least
amount of
energy?
Which color
has the least
amount of
energy?
Which color
has the
highest
amount of
energy?
The color of light observed when a substance is heated in a
flame varies from substance to substance.
Each element has a different electron configuration
as a result the color observed in the flame can be
used as a means of identification.
