Online Wavelength & Frequency Calculator
Instantly convert between wavelength and frequency of electromagnetic waves. An essential tool for students, physicists, and engineers in India working with the electromagnetic spectrum.
Wave Properties
Calculate wavelength or frequency.
Speed of Light (in vacuum)
This calculator uses the constant c = 299,792,458 m/s for calculations.
How to Use
- Select Mode: Choose whether you want to calculate Wavelength or Frequency.
- Enter Value: Input your known value (e.g., '550' for wavelength in nm).
- Select Units: Use the dropdown menus to select the correct units for both your input and desired output.
- Calculate: Click the "Calculate" button to see the instant result.
Example Calculation
Let's find the frequency of green light:
- Calculate For: Frequency
- Wavelength: 550 nm
The calculator will show that the corresponding frequency is approximately 5.45 x 10¹⁴ Hz (or 545 THz).
