Question

How do you measure wavelengths?

Answer 1

You measure wavelengths in meters (m)

Answer 2

Wavelength is measured by the distance between two points of the same phase

Step-by-step explanation:

Wavelength is measured by the distance between two points of the same phase in the wave, for example, between two consecutive maximum points or between two consecutive minimum points

The units used for measurement are meters, but it is very common to use nanometers or angstrom
