Interpretation Introduction

Interpretation:

The reason due to which semiconductor lasers have become common in many consumer applications is to be explained.

Concept introduction:

The distance between two consecutive crests of a wave of light is called the wavelength of light.

Materials that have a resistance level between a conductor and an insulator is called a semiconductor.

The diode is a semiconductor device that allows the flow of current in one direction only.
