SUMMARY

The color of light emitted by photons is determined by their wavelength, frequency, and energy. The relationships between these properties are defined by the equations c = λf, E = hf, and E = hc/λ, where c represents the speed of light, λ is the wavelength, f is the frequency, and h is Planck's constant. Understanding these relationships is crucial for comprehending how photons produce different colors of light.

PREREQUISITES
  • Understanding of basic physics concepts such as wavelength and frequency
  • Familiarity with Planck's constant and its significance in quantum mechanics
  • Knowledge of the speed of light and its role in electromagnetic theory
  • Basic mathematical skills to manipulate equations
NEXT STEPS
  • Research the implications of Planck's constant in quantum mechanics
  • Explore the electromagnetic spectrum and its relation to color perception
  • Learn about the applications of photon energy in technologies like lasers
  • Investigate how different materials interact with photons to produce color
USEFUL FOR

Students of physics, educators in science, and anyone interested in the fundamental principles of light and color theory.

i have read that light is made up of photons :smile: how does similar photons can produce lights of different colours(pardon me if this appears a silly question to u:redface:
 
Physics news on Phys.org
The color of a photon depends on its wavelength [itex]\lambda[/itex] or frequency [itex]f[/itex] or energy [itex]E[/itex] (take your pick). They're all related to each other:

[tex]c = \lambda f[/tex]

[tex]E = hf[/tex]

[tex]E = hc / \lambda[/tex]

where [itex]c[/itex] is the speed of light and [itex]h[/itex] is Planck's constant.
