# Planck's Energy of a Photon

**Formula:** `E = h × ν`

Planck's energy equation calculates the energy of a photon based on its frequency. In the equation, ** E** stands for the energy of the photon in joules,

**is Planck's constant (approximately 6.62607015 × 10**

*h*^{-34}Js), and

**(nu) is the frequency of the photon in hertz (Hz). The relationship shows that the energy of a photon is directly proportional to its frequency. This foundational concept of quantum mechanics demonstrates the particle-like behavior of light, where each photon carries a quantized amount of energy.**
