Step by Step Solution

Step1: Wavelength

The wavelength of a waveform signal conveyed in space or down a wire is the distance between identical points (consecutive crests) in adjacent cycles.

This length is commonly stated in meters (m), centimeters (cm), or millimeters (mm) in wireless systems (mm).

Step2: Find Wavelength

The wavelength utilized in the Michelson interferometer experiment can be expressed as

In our numerical example, we have
