Why Do Boats Make This Shape?
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...

Triangular prism splitting a ray of white light into its constituent colours.
This occurs because the light is refracted when it passes from the air to the glass, as the speed of light in glass is lower than that in air. Light with a shorter wavelength, at the blue end of the spectrum, is refracted more than the...
