Reflection Physics Waves: Laws, Types and Examples Guide

Reflection is the change in direction of a wave when it bounces off a surface. Light, sound, and water all reflect the same way — the angle at which they arrive equals the angle at which they leave.

Reflection, Refraction, and Diffraction: Compare All 3

Reflection, refraction and diffraction are the 3 ways waves change direction when they meet a boundary. Reflection bounces the wave back, refraction bends it through a new medium, and diffraction spreads it around obstacles. Here is how to tell them apart, with a comparison table and everyday examples.

What Happens When Light Hits a Mirror? Easy 5-Step Guide

When light hits a mirror, the photons interact with free electrons in the metal coating. The electrons absorb the incoming photon energy and re-emit it almost instantly, sending the light back at the same angle it arrived. Here is exactly what happens, step by step.

What Is Reflective Light? Simple Guide to 3 Types

Reflective light is light that has bounced off a surface and reached your eyes. Unlike incident light (the light arriving at a surface), reflective light carries information about the surface it hit — its colour, texture, and smoothness. Here is what reflective light is, how it works, and the 3 types you see every day.

When a Wave Bounces Off a Material: Easy Reflection Guide

Reflection is what happens when a wave bounces off a surface it cannot pass through. Light, sound, and water all reflect the same way — the angle of arrival equals the angle of departure.
