In an experiment, Davisson and Germer used electrons incident normally on a nickel crystal surface cut parallel to the principal Bragg planes. They observed constructive interference at an angle of 50 degrees to the normal to the surface. Find the wavelength associated with the electron beam. The inter atomic spacing of Ni is 2.15 Å. The given answer in my homework assignment is approximately 1.65 Å.

2. Write a computer program to find the roots of a general continuous function using the Newton-Raphson method. The mathematical function will be defined in the computer program as a function module. The inputs for the program should be the limits for the search xL and xU, and the specified allowable error, ers. Find the roots for the following equations and initial guesses for an specified allowable error ers = 1%\na. Function $f(x) = \sin(10x) + \cos(3x)$ with initial guess x = 4. How many step did you need to reach this answer?\nb. Function $f(x) = e^x - x$ with initial guess x = 1. How many step did you need to reach this answer?
