How Photons WorkFeature ArticlesAbout Us
If you've read How Photographic Film Works, you know that when film is exposed to light, the energy of the photons causes chemical changes in the silver halide grains coating the film. This creates a negative image of what you see through the viewfinder. With a photocopier, however, you ...

But wait. What makes a light source produce photons? We'll get to that. Next.Producing a Photon There are many different ways to produce photons, but all of them use the same mechanism inside an atom to do it. This mechanism involves the energizing of electrons orbiting each atom's nuc...

How do solar panels work? The photovoltaic cells in solar panels are those that have the capacity to generate electricity from the impact of solar radiation. These cells, which are usually made of crystalline silicon or gallium arsenide, are mixed with other components such as phosphorus or bor...
What is interference? How do interferometers work? What are the different types of interferometers? How accurate are interferometers? What are interferometers used for? Find out moreWhat is interference?To understand interferometry, you need to understand interference. In everyday life, interference simp...
Photons have no mass, but they still have (a tiny amount of) momentum, which is how solar sails work: the mind-boggling number of photons streaming off a star creates radiative pressure, which would move a spaceship powered by solar sails in the same way that an Earthly ship moves when ...

This process isn't like filling a bucket with water until a rubber duck floats over the rim. Absorbing an abundance of lower-energy photons won't do the trick for ionization. The electron won't budge until it absorbs a photon with the ionization energy. Just one photon with the necessary...
