  2. Enter the value in the appropriate field. Make sure to use scientific notation (e.g., 500e-9 for 500 nm).
  3. Click the "Calculate" button to get the frequency result.
  4. Use the "Reset" button to clear all inputs and start over.

Scientific Background

The frequency of light (f) is related to its wavelength (λ) by the equation f = c/λ, where c is the speed of light (approximately 3×10⁸ meters per second). Alternatively, it can be calculated from energy (E) using f = E/h, where h is Planck's constant.

Practical Applications

  • Calculating the frequency of visible light from its wavelength
  • Determining the frequency of light from its energy
  • Understanding the relationship between wavelength, frequency, and energy in electromagnetic spectrum
  • Used in physics and chemistry experiments involving light

Note: This calculator assumes standard SI units. For different units, appropriate conversions should be applied.
