In this lesson, we introduce the one dimensional wave equation and explore how it appears in electrodynamics. This video ...

An introduction to how Maxwell’s equations lead to electromagnetic plane waves. This lesson explains the physics behind wave ...

More than a century before quantum mechanics was born, Irish mathematician William Rowan Hamilton stumbled onto an idea that ...

Wavelength is defined, and students use the wave equation to solve problems. Wavelength is defined, and students use the wave equation to solve problems. Reflection is described at boundaries of ...

A century after Einstein predicted the outcome from a black hole collision, Frans Pretorius helped pave the way for the actual discovery of the ripples that would expand our understanding of the ...

For nearly a century, “reality” has been a murky concept. The laws of quantum physics seem to suggest that particles spend much of their time in a ghostly state, lacking even basic properties such as ...
