Calculate the wavelength and the frequency of the photons that have an energy of E_{photon} = 835 MeV. Calculate the wavelength and the frequency of the photons that have an energy of E_photon = 817 MeV. What is the energy of a photon that has a wavelength of 13.2 nm? What is t...
Then you get: E=mc2 (awesome)! Unrelated tangent: It took a little while, but the laws governing the massive and the massless are even more inter-related than the ‘Stein originally thought. He figured out that the energy of a photon is related to it’s frequency (E=hf), but why...
The energy spectrum of primary cosmic rays in the energy range of 10^14 10^16 eV is infered from the information about the electron/photon and muon components from the KASCADE array. We combine the EAS simulation program CORSIKA and a detector simulation program, based on the GEANT package,...
How to calculate photon energy from wavelength What is the Planck constant times the speed of light? What can travel faster than the speed of light? How long does it take to travel 500 light years? How far does light travel? What is the speed of light in air?
Dr Sue: [0:02:07] As a child, as a kid, I remember being able to see energy fields around people. It’s amazing to me that we live in a time where I get to talk about this because for many, many years I didn’t. I would ask my mom what’s that yellow thing following dad...
How to convert absolute cm-1to electron volts or eV We mentioned before that inverse cm are proportional to the photon energy. The energy of a photon ishc/lambda , so if you are working in eV and nm eV = 1.23984 x 103/nm So the photon energy in eV = 1.23984 x 10-4* cm-1 ...
The energy of each photon is inversely related to the wavelength of the light -- blue light is the most energetic, while red light has the least energy per photon of exposure. Ultraviolet light (UV) is more energetic, but invisible to human eyes. Infrared light is also invisible, but if...
Making a photocopy requires a light source with enough energy to boot electrons out of the photoconductive atoms. What wavelengths of light can do this? It turns out that most of the visible spectrum of light contains enough energy to drive the process, especially the green and blue end of ...
Max Planck Related Photon Wavelength to Energy The wavelength converter equation comes from the father of quantum theory, German physicist Max Planck. Around 1900, he introduced the idea of the quantum while studying the radiation emitted by a black body, which is a body that absorbs all incident...
