Web4 jun. 2024 · The wavelength of a 100mw laser is around 780 nm. The frequency of a 100mw laser is the number of wave crests that pass a given point in one second. The higher the frequency, the shorter the wavelength. The relationship between wavelength and frequency is given by the equation: wavelength = speed of light/frequency. WebSome laser measures, such as the Leica DISTO D510, can do this. However, other measures will only be suitable for one or the other. Distance Measurement – What will you be measuring?
