Calculate the energy of the green light emitted, per photon, by a mercury lamp with a frequency of 5.49x10 to the 14 th power Hz

For this problem, we have to use the Planck's equation.

E = hv

where

E is the energy

h is Planck's constant equal to 6.626*10⁻³⁴ J· s

v is the frequency in Hz or s ⁻¹

Applying the equation, the answer would be:

E = (6.626*10⁻³⁴ J·s) (5.49*10¹⁴ s⁻¹)

E = 3.64*10⁻¹⁹ J
