The conversion from hertz to joules is based on Planck's equation which relates the energy of a photon to its frequency. This calculation is fundamental in quantum mechanics and photon energy calculations.
The calculator uses the Planck-Einstein relation:
Where:
Explanation: The equation demonstrates that the energy of a photon is directly proportional to its electromagnetic frequency.
Details: Calculating photon energy is essential in various fields including quantum physics, spectroscopy, photochemistry, and telecommunications where light-matter interactions are studied.
Tips: Enter the frequency value in hertz (Hz). The frequency must be a positive value. The calculator will compute the corresponding energy in joules using Planck's constant.
Q1: What is Planck's constant?
A: Planck's constant (6.626 × 10⁻³⁴ J·s) is a fundamental physical constant that relates the energy of a photon to its frequency.
Q2: Can this calculator be used for all electromagnetic radiation?
A: Yes, the formula applies to all photons across the electromagnetic spectrum, from radio waves to gamma rays.
Q3: Why are the energy values so small?
A: Individual photons carry very small amounts of energy, which is why we use scientific notation with negative exponents.
Q4: How is this different from calculating wavelength energy?
A: For wavelength calculations, you would first convert wavelength to frequency using the formula f = c/λ, where c is the speed of light.
Q5: What practical applications does this calculation have?
A: This calculation is used in designing lasers, studying atomic spectra, photovoltaic cell research, and understanding quantum phenomena.
