AfL: Quantum Mechanics Assessment In this assessment, demonstrate your understanding of quantum mechanics by completing a problem set. Instructions Your task is to complete the questions in the problem set. Read each question carefully, identifying your given values. Show all formulas and calculations used to solve the problems. Report your answers to the correct number of significant digits and with the correct units Questions 1. A piece of sodium metal is illuminated with light of wavelength 355 nm. Considering sodium has a work function of 2. 46 ev, will electrons be ejected from the metal at this wavelength? Show calculations to justify your answer." 2. Gamma rays of wavelength 0. 0253 nm are scattered from a cesium target at an angle of 57" What is the wavelength of the scattered rays? 3. An electron has a kinetic energy of 4. 00 ev. What is its de Broglie wavelength? 4. The speed of an electron is measured at 5. 12 x 10 m/s to a precision of 0. 0200% What is the uncertainty in determining the position of this electron
