Frequently Asked Questions
What is photon energy?
Photon energy is the energy carried by a single photon, directly proportional to its frequency and inversely proportional to its wavelength. It's fundamental in understanding light-matter interactions.
How do I convert between eV and Joules?
Use the conversion factor: 1 eV = 1.602 × 10⁻¹⁹ J. Electron volts are commonly used in atomic and molecular physics, while Joules are the SI unit.
What is photon flux?
Photon flux is the number of photons passing through a given area per unit time. It's calculated by dividing laser power by individual photon energy.
Why is wave number important?
Wave number (reciprocal wavelength) is widely used in spectroscopy and represents the number of wavelengths per unit length, making it useful for energy level calculations.
