A laser pulse with wavelength 532 nm contains 3.85 mJ of energy. How many photons are in the laser pulse?
Added by Jeremy R.
Step 1
We know the energy of a single photon can be calculated using the formula: E = hf, where E is the energy, h is the Planck's constant (6.63 × 10^(-34) Js), and f is the frequency. Show more…
