Tasks

Move the sliders and discover how waves change. Earn up to 3 stars per task!

Set the amplitude to 2 (make the wave twice as tall). Task 1

Explore

Double the frequency to 2 (twice as many cycles). Task 2

Explore

Flip the wave upside down (negative amplitude). Task 3

Explore

Start with Double the Height to see what amplitude does, then explore frequency and wave flipping.

Tip: In y = a·sin(b·x), the parameter a controls amplitude (height) and b controls frequency (how many cycles fit). A negative a flips the wave upside down.
