🌟 Spotlight: From the tiny world of particles, let's surf into the mesmerizing universe of waves! 🏄‍♀️

🤔 What is it?

A wavefront is like the "frontline" of a wave. If waves were armies, wavefronts would be the first row of soldiers. For some waves, like water ripples, we can actually see these frontlines.

🌍 Real-world example

Imagine throwing a stone into a pond. Those circles that spread out? Yep, those are wavefronts. Each circle represents a point where the wave has the same phase.

🤔 What is it?

Rays are like the arrows that show the direction in which waves move. They are the imaginary lines pointing the way.

🌍 Real-world example

Think of a flashlight in the dark. The light beams are the rays that show which way the light is going. And guess what? If you shine that light on a mirror, the direction can change! 🪞
