2nd harmonic oscillation of a rope full with balloons — and announcing a summer break

On one of my very last days in my old job, I walked across campus and noticed this: I had to, of course, alert all my nearby friends! Especially since, on this engineering campus, apparently nobody else stopped to take a quick video. Seriously, what’s wrong with the world? I obviously had to come back at different […]

Velocity of shallow water waves.

The experiment we run to discuss the velocity of shallow water waves. In this post, I discussed how it took us several years to modify an experiment to make it both student and teacher-friendly. But what can you actually see in that experiment? The movies below show the type of standing waves that are excited […]

Seesawing of standing waves.

Improving one of the experiments run in the GEOF130 lab. One experiment that has been run in GEOF130 forever is the “standing wave”, where a wave is excited in a long and narrow tank and then, for different water depths, the period is measured and the velocity calculated in order to compare it to the […]

Standing waves.

A seesaw to visualize how standing waves move in an enclosed basin. In enclosed basins, standing waves can occur. In the simplest case, they have a node in the middle and the largest amplitudes at the edges of the basin. The movement of the water’s surface then closely resembles that of a seesaw. Extremely simple […]
