Please help, thank you! 4. Polarization of the Normal Modes of a Monatomic Bravais Lattice (a)...
question 7 and 8 Purpose To examine the properties of polarized light and the mathematical relationship describing the intensity of linearly polarized light (Malus'law). In addition, the lab will investigate different ways light can be polarized Overview This lab is the first of three labs exploring the properties of electromagnetic waves. Electromagnetic waves are composed of oscillating electric and magnetic fields. As discussed in the lecture the electric and magnetic field vectors are mutually perpendicular to each other. Light waves...
Could you please help me with part c? Thank you and have a great day! 1. A linear triatomic molecule can translate along the x, y and z axes. It also has rotational modes that have a nontrivial moment of inertia along two axis for which the rotational energy is E,--1,02L--,фг (the dot means a time derivative. these are the angular velocities about these two axes). Finally, it also has a vibrational energy E vib--11(d) 2 +-k(0x), associated with each...
Bottom pictures are 7.7 for context 7.4 Repeat the calculation of Section 7.7 for the empty lattice but for the foc case and the [111] direction. 7.7 The Empty Lattice and Simple Metals We again use our imaginary powers to control the strength of the potential. We assume a finite potential to define the lattice and then decrease it to an insignificantly low value so that the electrons become free. This is the empty lattice: it is a 'ghost' lattice,...
Reflection from Plane & Convave Mirrors Snell's n sin 02 Law n2 sine, For the plane mirror, we assume the mirror is placed on this page so that it stands vertically along the blue line below, with its length parallel to the page. Take the light source and arrange it to emit a ray of light that lies in the plane of this page. Cast the light ray onto the mirror, so that the ray hits the mirror at an...

AshcroftSolidState (... X 192 / 848 113% et 2. Density of Levels for a Two-Band Model To some extent this problem is artificial in that the effects of neglected Bragg planes can lead to corrections comparable to the deviations we shall find here from the free electron result. On the other hand, the problem is instructive in that the qualitative features are general. If we resolve q into its components paralle (9) and perpendicular (9.) to K, then (9.26) becomes...
Heres example 10.2 (3) (30 points) In Example 10.2, the moment of inertia tensor for a uniform solid cube of mass Mand side a is calculated for rotation about a corner of the cube. It also worked out the angular momentum of the cube when rotated about the x-axis - see Equation 10.51. (a) Find the total kinetic energy of the cube when rotated about the x-axis. (b) Example 10.4 finds the principal axes of this cube. It shows that...
hello, can you please help me out with number 3 and the rest of number 2 Thank you : ) My Notes 3. 1/4 points | Previous Answers ole is made of a rod of length d with charge +q on one end and -q on the other. You place it lying along the y-axis with its center at y> + d/2, 0) and the -q charge is at (0, y - d/2, 0). A test charge of magnitude +Q...
This is a problem about linearly polarized EM wave, please see the translation below. You only need to answer the first 2 questions, which are not too much for you. I appreciate and if you keep me posted, i will sure to give you a thumb up :D Suppose this wave is linearly polarized, with ε a unit vector define the direction of polarization and kI = kx the incident wave vector (a). Under what conditions do the vectors kI,...
Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
