How to find frequency from wavelength

To find the frequency (measured in hertz) from the wavelength (measured in meters), you can use the formula: frequency (Hz) = speed of light (m/s) / wavelength (m) The speed of light is approximately 3 x 10^8 meters per second, so you can plug that value into the formula and solve for the frequency. For example, if the wavelength is 0.01 meters, the frequency would be: 3 x 10^8 m/s / 0.01 m = 3 x 10^10 Hz This is the formula for electromagnetic waves in vacuum, for other mediums the speed of light should be replaced by the speed of light in that medium.
