standing wave – Adventures in Oceanography and Teaching

Such a pretty #friendlywaves!

My long time Twitter friend Anne shared these beautiful pictures and I absolutely had to do a #friendlywaves post where I explain other people’s wave pictures. Take a moment to admire the beautiful picture below. Wouldn’t you love to be there? I certainly would! What can we learn from this picture? First — it’s a windy […]

#wavewatching: Standing waves on coffee on a train!

When I wrote the blog post on “wave watching in a bucket” a couple of days ago, it strongly reminded me of a movie I had filmed already back in March 2018. I was sitting on a train, still inside the train station, and noticed the pattern in my mug (also I just had gotten my […]

A tiny waterfall, super- and subcritical flows, submerged hydraulic jump, standing waves. What more could anyone want?

Last stop on my work trip that — apart from doing important work, obviously — brought me to Berlin for some wave watching and to Brodowin to look at beaver dams: Eberswalde. Waiting for an appointment, I sat in the sun next to this adorable little waterfall and looked at so many nice examples of […]

Standing waves

One thing I find endlessly fascinating are – you might have heard it before – standing waves. At the waterfront in Kiel I saw some the other day: Watch the movie below and be fascinated, too! :-) Isn’t it amazing how wave crests and troughs seem to appear out of nowhere and vanish again? When we are so […]

Observing hydrodynamic phenomena on a creek

Looking at a creek on a Sunday stroll, and seeing lots and lots of concepts from hydrodynamics class. For example below, you see waves radiating from each of the ducks. And you see interference of waves from all those ducks. What happens if the ducks bring their waves closer? At some point, all those waves from […]

Standing waves in a tank

And really high order ones, too! On Monday, I showed you a movie on wave generation in Hamburg Ship Model Basin (HSVA)’s wave tank. At the end of that movie, we see that the wave energy is being dissipated by a “beach”. Well, we actually see that some of the energy is reflected in those cute little […]

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 […]
