Investigate the motion of waves in water, what happens when waves get reflected and different types of superposition of waves with this guide for KS3 physics students aged 11-14 from BBC Bitesize.

We say a message is incoherent when we can't make it out, or when it doesn't make sense. A scribbled note, a drunken argument ...

Consider two extreme types of water waves: ... A quantum object can be “in two places at once” by being in a so-called superposition of states. For waves, this is no surprise.

Regular waves are pretty straightforward – wind blows, water moves, surfers have fun. Square waves , however, are what happens when nature decides to get complicated.

The water manipulation technique is driven by waves. After studying computer simulations, the team used 3D-printed plastic structures to generate different kinds of waves in a water tank.
