Electron spin, matter waves and wave mechanics1) Usain Bolt can run the 100 meters in under 10 seconds. Lets say he weighs 200lb, give or take. Estimate his wavelength during a 100 meter race. Given your answer, is the wave-like nature of Usain Bolt observable? Will it play an important role in a 100m race?2) If an electron is bound to an atom, what is the maximum order of magnitude its wavelength can be? Explain why.3) Use the information given in Q3 to estimate smallest the velocity of an electron can be, and still be bound to an atom. What percentage of the speed of light is that? 4) write 2 references to be added at the end of homework.submit hand-drawn work (graphs, equations, etc) by taking photos of the work and uploading the images, that is acceptable so long as the work in the images is legible. NOTE 1: Show your working in all the questions below. NOTE 2: When making estimates, giving answers to within an order of magnitude sufficient. Answers should not contain any more than one significant figure (for example, in Q1, you answer should be along the lines of Usain Bolts wavelength is: 6 x 10^-9m and not 6.3247563x 10^-9m
