Πώς να υπολογίσετε το Photon Energy

Τι είναι το 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.

Τύπος

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)

Οδηγός βήμα προς βήμα

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