What determines the speed of a wave: the frequency, the wavelength, or the medium through which the wave travels? What can travel faster than the speed of light? What happens if we travel at the speed of light? How do we know the speed of light is constant?
A light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. Based on the semiconductor material used and the amount of doping, an LED will emit a coloured light at a particular spectral wavelength wh
Dispersion, sometimes more specifically called chromatic dispersion, occurs when the velocities of different components of a light wave depend on the wavelengths of those components. Specific types of chromatic dispersion are defined by what causes the dependence of velocity on wavelength. Types ...

Here we examine a fundamental question: do aeolian dunes stop growing and, if so, what determines their ultimate size? Earth’s major sand seas are populated by giant sand dunes, evolved over tens of thousands of years. We perform a global analysis of the topography of these giant dunes, ...
By identifying series of atomic absorption or emission lines that correspond to the same element, we can then measure how our observations are shifted in wavelength relative to the wavelengths we’d observe if that same atom were at rest in a laboratory. The shift, known as a redshift if it...
The wavelength is the length, in meters, of one full cycle of the wave. It can be measured as the distance between two consecutive crests or troughs. Next, we have the period, which is the time, in seconds, that it takes for one full wave cycle to pass a particular poin...
-3/2. the plus or minus determines the direction of intrinsic angular momentum particle will take. because bosons don't obey the pauli exclusion principle they are free to occupy the same quantum numbers, unlike 'unsocial' fermions. the dashed red line represents the formation of bose-einstein...
3. What is the role of photons in the electromagnetic spectrum? Photons make up the electromagnetic spectrum, which includes all forms of electromagnetic radiation, from radio waves to gamma rays. Each type of photon has a specific energy and wavelength, which determines its place on the spectrum...
