A
A quantum of light
3
Q
E = hf
E = hc
__
λ
A
Ε is the energy (J or eV)
h is Planck’s constant (6.63x10^-34 J•s or 4.14 x 10^-15 eV•s)
f is frequency (Hz)
λ is wavelength (m)
c is the speed of light (m/s)
4
Q
Blackbody
A
An object that absorbs all energy that contacts it when it is cool and emits (radiates) all wavelengths of light when hot.
5
Q
Planck’s experiment showed what?
A
Energy has to be quantized
6
Q
Quantized
A
Energy only occurs in whole number multiples of a basic amount.
