Students may think that they have no direct experience of quantum physics and its consequences. Nothing could be further from...
Class practical: Students use a diffraction grating as a tool for observing the spectra from a variety of light sources.
Demonstration: Using a spectrometer to observe the absorption lines formed when white light passes through sodium vapour.
Demonstration: Observing the spectra from a variety of light sources.
Spectra are beautiful things to see. The full spectrum of white light blazing across a screen is a surprise and a delight to...
What we know about the universe comes from observations which rely on the radiation and (to a lesser degree) particles which...
This episode discusses: quantisation; energy levels in a hydrogen atom; and, distinguishing quantisation and continuity. And...
The British physicist, Henry Moseley, showed that every element had a unique X-ray emission spectrum.
