Waves and optics

What you'll learn

1. 1

   Imagine dropping a pebble into a still pond — ripples spread out in circles. Those ripples are waves! 🌊

2. 2

   What do waves carry from one place to another? 🌊

3. 3

   Watch these waves on a screen — drag the slider to change their height (amplitude).

4. 4

   Let's find the wavelength of this wave — the distance between two peaks.

5. 5

   Drag the wave to match a wavelength of 4 units on the ruler.

6. 6

   What do we call the distance between two wave peaks? 🌊

7. 7

   If you increase the amplitude, what happens to the wave's energy? ⚡
