In this video Paul Andersen explains how the wavelength is the distance between oscillations in a wave. In a longitudinal wave this might be the distance between areas of compression. In a transverse wave it might be the distance between...

The heights of a dual gravity drained tank are solved with the Scipy.integrate function ODEINT. This example demonstrates how to solve the differential equation and plot the solution.

Each kind of light has a unique wavelength, but human eyes can only perceive a tiny slice of the full spectrum -- the very narrow range from red to violet. Microwaves, radio waves, x-rays and more are hiding, invisible, just beyond our...

Hank's news this week informs us on a couple of crazy science experiments, updates us on some earlier topics (dangerous asteroids and ancient phallic rock art), and briefs us on a new study that seeks to find the evolutionary origins of...

In this video Paul Andersen details the waves in electromagnetic radiation. There is an inverse relation between the wavelength and frequency of electromagnetic waves. Electromagnetic radiation includes gamma rays, x-rays, infrared...
