This video is about the "Kelvin wake" shape of water wakes behind boats - we talk about mach angle, dispersion, superposition of many waves, and how these all lead to the pattern of a wake. We don't get into Froude number though...

In this video Paul Andersen explains how the perceived frequency of a source depends on the motion of both the source and the observer. As a source approaches an observer the frequency will increase and as it moves away it will...

In this video Paul Andersen explains how waves will diffract (or bend) around an obstacle or while traveling through and opening. Diffraction will be maximized when the size of the opening or obstacle matches the wavelength.

Frequency is the measurement of the total number of complete cycles or oscillations that a wave goes through in one second, and it is expressed in hertz (Hz). Frequency is a fundamental attribute that dictates the rate at which a wave...

This is a lecture video that explains various methods used to measure the speed of waves. The video starts by introducing two equations that can be used to calculate the wave speed. It then focuses on two examples to explain how to use...

This nugget explains the source, generation, properties and discovery of electromagnetic waves.

In this video, the speaker discusses different types of renewable energy resources including hydroelectric energy, wind power, solar energy, biofuels, tidal power, water waves, and geothermal power. The speaker explains the advantages...
