SUMMARY

The discussion centers on the relationship between angular frequency and wavelength in electromagnetic waves. Participants confirm that the angular frequency, represented by the equation ω = 2πf, can indeed be used to determine wavelength by rearranging the formula E = hf = (hc/λ). This approach is valid as it connects the concepts of frequency and wavelength, affirming that both equations can be utilized interchangeably in the context of electromagnetic waves.

PREREQUISITES
  • Understanding of angular frequency (ω) and its relation to frequency (f).
  • Familiarity with the equation E = hf, where E is energy and h is Planck's constant.
  • Knowledge of the speed of light (c) and its relationship to wavelength (λ) and frequency (f).
  • Basic principles of electromagnetic wave theory.
NEXT STEPS
  • Study the derivation and implications of the equation ω = 2πf in electromagnetic contexts.
  • Explore the relationship between energy, frequency, and wavelength using E = hf and c = λf.
  • Investigate the properties of photons and their role in electromagnetic radiation.
  • Learn about the applications of angular frequency in various fields of physics.
USEFUL FOR

Students of physics, educators teaching electromagnetic theory, and professionals working in fields related to optics and wave mechanics.

Hi all,
can the angular frequency of a electric waves be used to determine the wavelength using the following;
ω=2πf
rearranging for the frequency, and using the following;

E=hf=(hc/λ)

or can this formula no be used as it is dealing with photons?

yep, that's fine. all you're really doing is using the two equations: ##\omega = 2 \pi f## and ##c=\lambda f##.
