Kaip apskaičiuoti Photon Energy

Kas yra Photon Energy?

Photon energy is the energy carried by a single light photon. Higher frequency (shorter wavelength) = more energy per photon. X-rays carry thousands of times more energy than visible light.

Formulė

E = hf | E = hc/λ | where h = 6.626×10⁻³⁴ J·s, c = 3×10⁸ m/s, f = frequency, λ = wavelength

E: Photon energy (J or eV)
h: Planck constant (6.626×10⁻³⁴ J·s)
f: Frequency (Hz)
λ: Wavelength (m)
c: Speed of light (3×10⁸ m/s)

Žingsnis po žingsnio vadovas

1E = hf (Planck's equation)
2E = hc/λ (from wave equation c = fλ)
3h = 6.626×10⁻³⁴ J·s; c = 3×10⁸ m/s
4Convert to eV: 1 eV = 1.6×10⁻¹⁹ J
