For this project I show how to make make a pendulum wave, an interesting science/physics experiment where a series of pendulums is measured so that each one moves slightly faster than the one before ...

Thomas Young’s double-slit experiment is famous for demonstrating the principle of interference. Andrew Murray explains why it’s now possible to carry out an equivalent experiment using lasers that ...
