What is the energy contained in each photon emitted by the laser?

Energy of Laser Photons

The energy contained in each photon emitted by the laser is 3.14×10^-19 J.

Photons emitted by a laser carry a specific amount of energy, which can be calculated based on the laser's intensity. In this case, each photon emitted by the laser contains approximately 3.14×10^-19 joules of energy.

The energy of a photon can be determined using the formula E = h * f, where E is the energy, h is Planck's constant (6.63 x 10^-34 J·s), and f is the frequency of light. The frequency of light can be calculated using the formula f = c / λ, where c is the speed of light (approximately 3.00 x 10^8 m/s) and λ is the wavelength of the light.

Given the wavelength of the laser light is 633 nm (633 x 10^-9 m), we can calculate the frequency of the light to be approximately 4.74 x 10^14 Hz. Substituting this frequency value into the energy formula, we find that each photon emitted by the laser contains around 3.14×10^-19 joules of energy.
