Hot key a probe (control, 1) then if there is a light switch turn the lights off. There has to be a light switch for stacking. After the lights are off press 1. This will select your probe. Then you can make cannons and other buildings on top of each other.
They destroy each other and create a gamma photon.
(The energy of each photon) is (the photon's frequency) times (Planck's Konstant). (The total energy in a beam of it) is (the energy of each photon) times (the number of photons in the beam).
Because at their frequencies, each gamma ray photon has more energy than a photon of any other form of electromagnetic radiation.
Each photon of blue light has more energy than a photon of any other color, because the blue ones have the highest frequency.
Photons do not become "entangled" with each other any more than waves on water do. They move along independently. If a photon crosses the event horizon of a black hole as that photon follows the curve of spacetime "down" into the black hole, it is probable that a photon moving "with" it will suffer the same fate.
It depends on the wavelength of the photon. Energy of each photon is hc/λ, where h = Planck's constant = 6.626x1034 Js, c = speed of light = 3x108 m/s, and λ = wavelength of the photon
A Royal Salute that is performed at military functions and funerals has 21 guns that fire. If cannons are used it is usually a series of seven cannons that are fired three times each. The common method is to have seven soldiers fire a rifle three times each.
photon
Each photon has a specific amount of energy.
Max Planck came up with the idea of a photon of energy, suggesting that instead of waves, each photon had a discrete amount, or a quantum hence the foundation of quantum mechanics. I assume it was him who gave it the name.
Light waves are made up of electrical waves and magnetic waves that are perpendicular to each other and support each other, they are also perpendicular to the direction the waves are traveling so there are no vibrations in the direction the light travels.
They differ in frequency. (That's exactly the same thing as saying that they differ in wavelength, since frequency and wavelength are firmly connected.) (That's also the same thing as saying that they differ in the quantity of energy carried by each photon, since the amount of energy carried by each photon is firmly connected to frequency.)
