1. Concept Overview When a stone is dropped into a pond, we see ripples spreading outward. Every point on a…

1. Concept Overview To understand how light travels, bends, or spreads, we need a simple idea called Huygens’ Principle. It

1. Concept Overview (Beginner-Friendly) When a wave (like light) strikes a smooth surface such as a mirror, it does not

1. Concept Overview When a wave (e.g., light) travels from one medium into another (say from air into water), its

1. Statement of the Principle The Superposition Principle states: When two or more waves overlap at a point in space,

Concept Overview Young’s Double Slit Experiment is a famous experiment that proved the wave nature of light. It demonstrates interference,

Concept Overview When two or more waves meet at a point, they superpose. This superposition leads to either: Increase in
