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

1. What is the scientific discipline?Branch of Physics
2. What is the fundamental models?Geometric optics (rays) and physical optics (waves)
3. What is optics and why is it important?Optics is the study of light and how it moves, bends, and helps us see everything around us. It helps scientists build telescopes, cameras, and even eyeglasses.
4. How does light bend when it goes from air into water?Light bends, or refracts, when it travels from one material to another with a different density. This bending follows Snell's Law and is why objects look bent in a glass of water.

Electromagnetic Spectrum: The range of all types of electromagnetic radiation, ordered by frequency and wavelength.
Refraction: The bending of light as it passes from one medium to another, due to a change in speed.
Diffraction: The bending and spreading of light waves as they pass through an opening or around an obstacle.
Photon: A quantum of electromagnetic energy, behaving as a discrete particle of light.
