4. A red laser pointer emits light that has a wavelength (2) of 651 nm (nanometers). (A) Calculate the energy (Ephoton) of a single red light photon emitted by the laser pointer in units of Joules. Hints: There is a unit conversion involved in the problem for 'nanometers' to meters. Which equation from Chapter 5 should we use to solve for the energy here? What is the value of the Planck's constant (h)? Show work for each step. Include units and observe proper sig figs and rounding in your answer. (B) If the red laser pointer in part (A) yields 3680 J of energy at a time, how many moles of red light photons are emitted by it? Hint: Avogadro's number is involved in this calculation. Show work for each step. Include units and observe proper sig figs and rounding in your answer.
