How many photons are produced in a laser pulse of 0.616 J at 529 nm?

Expert Solution

To calculate the number of photons in the given laser pulse we first calculate the energy associated with one photon.

Energy of one photon can be calculated using the Plank Einstein relation,

where E is the energy of one photon, h is the planks constant (6.626 10^-34 Js), c is the speed of light (310⁸ m/s) and is the given wavelength

= 529 nm = 529 10^-9 m [1 nm= 10^-9 m]

Number of photons produced in the laser pulse = Energy of the laser pulse / Energy of one photon
