8. [15 points] Consider 3 identical long slits parallel to each other with distance $d$ between adjacent slits. These slits are narrow enough that the effect of diffraction is negligible. A laser with wavelength $\lambda$, assumed to be a plane wave with coherent phase, is incident directly on the slits, and produces an interference pattern on a distant screen. (a) Let $\phi$ be the phase difference between waves from adjacent slits arriving at a point on the screen, which is at an angle $\theta$ from the original direction of the beam. Show that $\phi = \frac{2\pi d}{\lambda} \sin \theta$. (b) Let $E_0$ be the electric field amplitude of the wave from individual slit. Draw a phasor diagram for the total wave, and show that its electric field amplitude is given by $E_{tot} = E_0(1 + 2 \cos \phi)$. (c) Calculate and plot the intensity that is measured on the screen as a function of $\phi$. (Hint: Do not forget that intensity is proportional to square of electric field amplitude.)

In the absence of defect broadening, estimate the highest temperature at which SdH oscillations would be observable in the sample described above with B ? 4T. Conversely, in the absence of thermal fluctuations, estimate the highest defect scattering rate that would allow measurement of SdH oscillations at this value of the field. Express your answer in terms of allowed values for $\tau_f$, the mean time between scattering events for electrons.

Problem: Find the root greater than zero for the following equation using the Secant Method and compare the result with MATLAB's fzero function. e^{0.5x} = 5 - 4x^3 Write a main program and a function program (see requirements) Requirement: 1. Main Program a. define function handle for the equation you are finding the root for b. define es based on 4 significant figures c. use input statements to have the user enter two initial guesses Enter first guess for the root: Enter second guess for the root: d. call function program to estimate root using Secant Method e. calculate root using matlab's fzero function (r = fzero(f,x1), where 'f' is the function handle, and x1 is the first initial guess of the root) f. output results as follows Using fzero the root of the equation is: #.##### Using the Secant Method the root of the equation is: #.##### It too # iterations for the Secant Method to converge. 2. Function Program (algorithm for Secant Method) a. algorithm for Secant Method b. name your function program sec_method c. inputs to your function will be es, x1, x2, and your function handle (where x1 and x2 are the initial guesses) d. outputs will be the root and the number of iterations. Example: Enter first guess for the root: 2 Enter second guess for the root: 2.2 Using fzero the root of the equation is: 0.94677 Using the Secant Method the root of the equation is: 0.94677 It took 7 iterations for the Secant Method to converge.
