Know why the speed of sound increases with temperature. Know how the color of a light source affects the apparent color of an object. Know what kind of cells is responsible for color vision. Know what kind of image can be projected onto a screen placed at the apparent position of the image. Know the primary colors of light. Know what kind of image is created by a plane (flat) mirror. Know which portion of the electromagnetic spectrum has the shortest wavelengths? Know what a particle of light is called. Know what kind of pattern forms on a screen when laser light passes through a narrow slit on its way to a screen. Know what ability of particles of light causes electricity to flow in some materials. Know which portion of the electromagnetic spectrum has the most energy per photon. Know what the energy of a photon is proportional to. Know how we refer to the nature of light. Be able to tell one thing that supports the theory that light is a wave and another that supports the theory that light is a particle. Know what was shown by Rutherford’s “gold foil” experiment. Know what happens when an electron jumps from one orbit to a more stable one. Know how many electrons each energy level can hold. Know what particles an atom is made of and where each type of particle is located within the atom. Know what keeps the electrons in the atom. Know what holds the nucleus together. Know what formula tells the energy of a photon. Know what formula tells the momentum of a photon. Know how many quantum numbers are needed to describe an electron. Know what each of those quantum numbers tells. Be able to calculate the De Broglie wavelength of particle given its speed and mass. Be able to calculate the momentum of a photon given its wavelength.
