SUMMARY

The equation E = hf, where E represents energy and f denotes frequency, accurately describes the energy of photons. This relationship indicates that the energy of a photon is directly proportional to its frequency, confirming that light behaves as a wave. Despite this wave-like behavior, photons travel in straight lines, demonstrating their particle nature. This duality is fundamental in understanding the behavior of light in various contexts, including quantum mechanics.

PREREQUISITES
  • Understanding of quantum mechanics principles
  • Familiarity with wave-particle duality
  • Basic knowledge of electromagnetic radiation
  • Concept of frequency in physics
NEXT STEPS

How is the equation E = hf able to describe how much energy photons have? f is frequency, implying that light is a wave, but photons move in straight lines.
