Step by Step Solution

Step 1: Introduction

X - rays are electromagnetic wave that allows the human eye to see or make objects visible. It can also be considered as radiation that can be seen with the naked eye. Photons are tiny packets of energy that make up light.

Step 2: Explanation

The path length is raised or lowered by when a mirror is moved by . Because one mirror is pushed in and the other is moved out, the path length difference is increased by .The entire difference in route length is , which is equal to the wavelength of light. As a response, the spot will continue bright because no net difference in phase difference was generated.
