![]() ![]() Often achieving this state requires that the atoms “share” electrons in their shells. The electrons move to position themselves to exist at their lowest possible energy. When an atom comes near another atom, their electron shells interact. The further away an electron is from the nucleus, the higher energy it is - just like when you stretch a rubber band. ![]() Electrons in atoms tend towards their lowest possible energy state - they try to be as close as possible to the nucleus. If the photon has less energy, the wavelength it creates will be longer. If the photon has a lot of energy, the ripples will be closer together, that is, the wavelength will be shorter. The distance between each ripple in the waves is called wavelength. The amount of energy an individual photon carries affects the shape of the waves it creates. Light is also a wave because, as a photon travels, it creates waves in the electromagnetic field. Individual photons can vary in how much energy they carry. The particle part of light is called a photon. Light is interesting because it behaves both like a particle and a wave. Light is energy that is traveling through the electromagnetic field. Together, the two fields make up what’s called the electromagnetic field. The way these charged particles interact when they are in motion is called the magnetic field. ![]() The way these charged particles attract and repel each other is called the electric field. To truly understand color we must first understand light. ![]()
