The key is presented at the bottom of the exam. Multiple Choice 1. The product of wavelength and frequency of light is a constant. As the energy increases, the frequency of the radiation decreases. As the wavelength of light increases, the frequency increases.
Red light has a higher frequency than blue light.
Light is considered to have only wave character. Calculate the minimum frequency of light that is required to ionize a cesium atom. The square of the wave function, Y , of an electron in an atom a. describes the energy of the electron. The two quantum numbers which represent a 3d electron are a. The measure of the attraction that an atom has for the electrons in a chemical bond is called a. electron affinity.
