Photon Energy

\[ E=h\cdot f \]

\[ E=0 \text{ J} \]

Understanding the Energy of Photons:
Two fundamental equations describe the energy of photons, which are particles of light:

  1. \( E = h \cdot f \)
    • \( E \): Energy of a photon.
    • \( h \): Planck's constant, a fundamental constant in quantum mechanics.
    • \( f \): Frequency of the photon.

  2. \( E = h\cdot\frac{c}{\lambda}\)
    • \( E \): Energy of a photon.
    • \( h \): Planck's constant.
    • \( c \): Speed of light in a vacuum.
    • \( \lambda \): Wavelength of the photon.

  • \( E = h \cdot f \):
    • This equation states that the energy of a photon is directly proportional to its frequency. As the frequency of a photon increases, its energy also increases.

  • \( E = h\cdot\frac{c}{\lambda}\):
    • This equation shows that the energy of a photon is inversely proportional to its wavelength. Shorter wavelengths correspond to higher energy photons.

These equations are pivotal in understanding the fundamental relationship between the energy of photons and their frequency or wavelength. They are crucial in various fields such as quantum mechanics, optics, and photonics.

Understanding the energy of photons is essential in fields like quantum physics, where these equations help in explaining phenomena related to light, such as the photoelectric effect, emission spectra, and the behavior of electromagnetic radiation.
