The
Energy of Photon
-
The color or energy of the
light is determined by its frequency, n
(think of sneezing).
E
= hn
-
h is Planck's constant,
in honor of Max Planck
h = 6.625
x10-34 J s
n =
c/l
E
= hc / l
-
Example:
WERN at 88.6 MHz
E
= (6.625 x10-34 J s )(88.6 x 106 1/s)
E = 5.8 x 10-26
J
l =
(3 x 108 m/s ) / (88.6 x 106 1/s)
l =
3.39 m
