Solution: How many photons are produced in a laser pulse of 0.528 J at 679 nm?
Problem
Solution
Since we have a value for wavelength, we will use the equation E=hv where E is energy, h is Planck's constant and v as frequency.
Frequency (v) can be solved by dividing the speed of light c by the wavelength in meters: v = c/λ
