Wavelength Calculator

How to Use This Tool

This tool calculates wavelengths using frequency and speed. The process is simple.

  1. Enter a frequency value into the field. Use any positive number.
  2. Select the frequency unit. Options include Hz, kHz, MHz, GHz, and THz.
  3. Type a wave speed value in the wave velocity field. The default is set to the speed of light in vacuum.
  4. You may choose a preset value from the list. This list covers speeds in air, water, glass, or sound speeds in various media.
  5. Pick your preferred unit for the result. You can choose from picometers, nanometers, micrometers, millimeters, centimeters, meters, or kilometers.
  6. Press the calculate button to see the wavelength.

Input Field Explanations

The frequency field accepts a positive number. The unit selector helps you choose the correct measure.

The wave velocity field works similarly. You can manually enter a value or pick a preset.

The result unit field lets you see the result in your chosen unit. The tool converts the value for display.

Understanding the Output

The tool displays the wavelength after you press calculate.

A formula appears below the result. It shows how the wavelength is calculated.

The result appears in the unit you selected. Short values may use scientific notation.

Limitations and Special Notes

Only positive numbers are accepted for frequency and speed.

The tool works best when you choose the correct units.

Scientific notation might show up when the wavelength is very small.

Common Use Cases

This calculator is useful in physics labs and classrooms.

It can help when studying light or sound waves.

Engineers may use it for design calculations in telecommunications.

Common Questions

What is a wavelength? A wavelength is the gap between two similar points on a wave.

Can I change the speed value? Yes. Use the preset values or type a custom value to match your scenario.
