Question

Calculate the frequency (in s–1) of a gamma ray photon that has an energy of 3.33 x10–13 J

Answer 1

Use the formula E = hv

E = energy = 3.33x10^-13 J

h = Planks constant = 6.626x10^-34 J-sec

v = frequency = ?

3.33x10^-13 J = (6.626x10^-34 J-sec) v

v = 3.33x10^-13 J / 6.626x10^-34 J-sec

v = 5.03x10²⁰ sec^-1
