Question
Check my answer, I am afraid I skipped something in question 10. What is the above FREQUENCY/WAVELENGTH for one photon and one mole?
A light beam traveling in air with a wavelength of 600 nm falls on a glass block. What is the frequency of the
light beam in glass? (c = 3x108 m/s)
9.
Step one: convert nm tom
1 m
= 6 x 10-7m
600 nm :
109 nm
Step two: Use formula v =
to solve for frequency
3.00 x 108 m/s
v =
= 5 x 1014HZ
6 x 10-7m
10. What is the energy for the above frequency / wavelength for one photon and one mole?
Step one: Use formula E =
h•c
to solve for energy, using the meter conversion forl from the above
problem
(6.626 x 10-34 J*s)(3.00 x10®m/s)
E =
= 3 x 10-19.
6 x 10-7m
Step two: Convert J to J/mol
6.02 x 1023J
3 x 10-19J ·
= 2 x 105 J/mol
