Homework Statement
I had to find wavelenght and linear momenta of fotons with energies of 3eV, 50 KeV and 1.0 MeV
Are these correct?
Homework Equations
E=hc/λóλ=hc/E and p= h/ λ
The Attempt at a Solution
a. 3eV Hence λ=(6.63E-34*3E8)/3=6.63E-26m
p = 6.63E-34/6.63E-26 = 1E-8
b. 50 KeV = 50000 eVλ=(6.63E-34*3E8)/ 50000 =3.978E-30m
p = 6.63E-34/3.978E-30 = 1.66E-4
c. 1.0 MeV = 1 000000 eVλ=(6.63E-34*3E8)/ 1 000000 = 1.989E-31m
p = 6.63E-34/1.989E-31 = 0.0033
