How to Use This Calculator

  1. Choose which method to calculate frequency:
    • Enter Wavelength (λ) to calculate frequency using f = c/λ
    • Enter Energy (E) to calculate frequency using f = E/h
  2. For wavelength calculations, input the wavelength in meters (m). The calculator will use the speed of light in vacuum (c = 299,792,458 m/s) by default.
  3. For energy calculations, input the energy in Joules (J). The calculator will use Planck's constant (h = 6.626 × 10-34 J·s) by default.
  4. Click the Calculate button to compute the frequency in Hertz (Hz).
  5. The result will be displayed in scientific notation with 6 significant figures.
  6. Click Reset to clear all input fields and start over.

Understanding Electromagnetic Radiation

Electromagnetic radiation consists of waves of electric and magnetic fields that propagate through space and carry energy. The frequency (f) of electromagnetic radiation is the number of complete wave cycles that pass a given point per second, measured in Hertz (Hz).

The relationship between frequency and wavelength (λ) is given by:

f = c/λ

where c is the speed of light in vacuum (approximately 299,792,458 meters per second).

The relationship between frequency and energy (E) is given by:

f = E/h

where h is Planck's constant (approximately 6.626 × 10-34 Joule-seconds).
