C h . 7 H o n C h e m H W #44 HC 1 of 3 A2) An FM radio station broadcasts at 99.5 MHz. Calculate the wavelength of the corresponding radio waves. A3) Microwave radiation has a wavelength on the order of 1.0 cm. Calculate the frequency and the energy of a single photon of this radiation. Calculate the energy of an Avogadro’s number (mol) of photons (called an Einstein ,) of this radiation.

#44 HC 2 of 3 A5) The work function of an element is the energy required to remove an electron from the surface of the solid element. The work function for lithium is 279.7 kj/mol (that is, it takes 279.9 kj/mol of energy to remove one mole of electrons from one mole of Li atoms on the surface of Li metal {Einstein’s Photoelectric Effect}. What is the maximum wavelength of light that can remove an electron from an atom on the surface of lithium metal?
