Answers below are taken from the article’s stored facts, so they match what the student read.

1. How big is Light beam?Optical communication systems extensively use light beams guided through fiber optics
2. What is a light beam?A light beam is a straight, focused line of light that travels in one direction, like a flashlight or a laser. It is different from ordinary light that spreads out in all directions.
3. How is a light beam different from regular light?Regular light scatters in many directions, while a light beam stays close together and moves straight. This makes the beam bright and easy to see in a specific path.

Electromagnetic Radiation: Energy that travels in waves, including visible light, radio waves, and X-rays.
Collimation: The process of making light rays parallel to form a focused beam.
Stimulated Emission: The process by which an excited atom releases a photon when struck by a photon of the same energy, fundamental to lasers.
Coherence: A property of waves where their crests and troughs align, characteristic of laser light.
