This is a converter for units of electromagnetic waves (light, radio waves ...).

Usage: Type the value of the wavelength, frequency, or energy you want to convert into the field behind which you find the unit. Click on any empty space in the window or on the "calculate" button. Read the result in the other fields. Move the mouse over a unit or click on it to read its full name. Use the "reset" button to reset your calculation.

Example: Which wavelength has a radio wave with the frequency of 6075 kHz? Type "6075" into the field in front of "kHz". Click on any empty space in the window or on the "calculate" button. Find your result in the field in front of "m" (49.349 m).
What is the energy of radiation of 300 nm (UV-B)? Type "300" into the field in front of "nm". Click on any empty space in the window or on the "calculate" button. Find your result in the field in front of "kJ/mol" (398.76 kJ/mol).

Remarks:
- Please note the remarks about the representation of numbers..
- There is no warranty for the calculation. Cactus2000 is not responsible for damage of any kind caused by wrong results.
- Please send an email if you have suggestions or if you would like to see more conversions to be included.
