cesium is used extensively in photocells and in television cameras because it has lowest ionization energy of all the stable elements.a) what is the maximum kinetic energy of a photo electron ejected from cesium by 555nm light? note that if the wavelength of the light used to irradiate the cesium surface become longer than 600 nm, no photoelectrons are emitted.B) use the rest mass of the electron to calculate the velocity of the photoelectron in(a).
