IDENTIFY the relevant concepts

The diamond layer can be treated as a thin film in which light is reflected from both the front surface $($the substrate$-$diamond interface$)$ and the back surface $($the diamond$-$vacuum interface$).$ As the thickness of the layer increases, the path difference between the reflected rays changes, affecting the way in which they interfere. When the rays interfere constructively, a maximum in the intensity of light, or a bright fringe, is observed at the center of the screen; when the rays interfere destructively, the intensity of light at the center of the screen decreases to zero and a dark fringe is observed. Therefore, the thickness of the layer is related to the number and type of fringes observed on the screen during the growth process.

SET UP the problem using the following steps

Part A

The diagram below shows the incident ray from the laser passing through the substrate and the diamond film. Assume that the incident ray strikes the interface at near$-$normal incidence, although it is drawn at a small angle for clarity.

Draw the ray reflected from the substrate$-$diamond interface $($Ray $1)$ and the ray reflected from the diamond$-$vacuum interface $($Ray $2),$ ignoring the effects of refraction.

Select the elements from the list and add them to the canvas setting the appropriate attributes. Press CTRL$+$M to get to the main menu. There is an image on the canvas: A laser beam moves upward and to the right first through horizontal layers of a substrate and then through a diamond in the same direction in both media. There is vacuum above the diamond layer. The diamond layer has a lesser thickness than the substrate layer. A horizontal screen is placed beneath the substrate layer to the right from the laser beam's starting point.
