300
what is the wavelength of an x-ray with a frequency of 5.63 x 1019 hz?
C=λv
C= 3.00x108m/s
v=5.63x1019hz
λ=3.00x108/5.63x1019=5.33x10-12m

A photon of red light has a frequency of 4.7 x 1014hz what is the energy of the photon?
E=hv
h=6.626 x 10-34 Js
c=4.74 x 1014hz
E=6.626x10-34 x 4.74x1014 = 3.14x10-19J
400

Draw the dot structure for oxygen.
500
what is the wavelength of a photon with an energy of 5.23x10-19?
E=hv
C=λv or v=c/λ
so E=hc/λ
E=5.23x10-19 J, C=3.00x108m/s, h=6.626x10^-34Js
λ = (3.00x108 x 6.626x10-34)/5.25x10-19=3.79 x10-7M
