4. (4.5 pts) Consider a 3D electromagnetic plane wave in vacuum, described in usual complex form by, (r, t) = Ēelkr-wt) in which ło = Epein/2y. Where k = -kx is the wave vector (assume k > 0) and w > 0 is the angular frequency. As usual, the real field is Er, t) = ReLEr, t)] (a) In which direction is the wave propagating? In terms of the given values k and w, what is the speed, wavelength, and...
Question 1: As you work through the parts of this question you are going to show that the Maxwell equations naturally contain electromagnetic waves. In a region of space that is void of all charges and currents, p=0 and J = 0 the Maxwell equations come out to be: Y E = 0 7.B=0 7 x Ē = -1 1 x B = Poco a) Using the same idea as I did in the lecture, derive the Wave Equation for...
PLEASE SHOW AND EXPLAIN ALL STEPS FOR ALL 3 PARTS......I'M LOST......THANKS SO MUCH!! r 1 Given the vector field in space F(x, y, z) = xi + yj + zk or more conveniently, (x2 + y2 + 22)3/2 F(r) =3 = f where r = xi + yj + zk and r = = 1|r1| Vr2 + y2 + x2 (instead of p) (a) (10 pts) Find the divergence of F, that is, V.F. =V (b) (10 pts) Directly evaluate...
please give me the answer to all of them thank you 8. -0 points My Notes Ask Your Teacher A particle with a mass of 0.340 kg is attached to a horizontal spring with a force constant of 3.0ō N m At the moment t moving to the left. (Assume that the positive direction is to the right.) 0 the partice has s maximum speed of 75ms and s (a) Determine the particle's equation of motion, specifying its position as...
Please show and explain your steps and please show the graph the before and after the transformation like in the picture, thank you. 12. Use the transformation T: u = -x and v=ķy to evaluate the integral ſf xdA where R is the region R bounded on the xy-plane by the ellipse 9x² + 4y2 = 36. . Let S be the image of R under T on the uv-plane. Sketch regions R and S. Set up the integral 7as...
Please show all steps, I'm practicing for an exam. Thanks!! The path of a fighter jet is described by r (t) = (10−3t^2) i − (5/t^2) j + te^(3−3t) k , where distances are measured in kilometers (km) and t in minutes (min). A laser is fired in the tangential direction toward a target on the x-axis at the time t0 = 1. (a) What point on the x-axis does the laser hit? (b) Suppose the laser travels twice the...
please explain all, thanks! 4. (60 pts) A particle in an infinite square well of width L has an initial wave function (x,t = 0) = Ax(L - x)2, OSX SL a) Find y(x, t) fort > 0. You first have to normalize the wave function. Hint: this is best expressed an infinite series: show that the wave function coefficients are on = * 31% (12 – n?)(1-(-1)") → (n = 87315 (12 - nºre?); n odd. b) Which energy...
Please Help! If possible show every step my biggest issue is understanding how to get rid of the Bessel Function. Thank you! We've seen that the wave equation takes the form 1 af 2 12 = 0, where V2 is the Laplacian, v is the wave velocity, and f is the function describing the wave. In two Cartesian dimensions the Laplacian reduces to V2 f = 0f + 3f, which is a very convenient form for solving systems with rectangular...

The effect of air resistance is represented by the damping coefficient b = 3.00 N-s/m (a) Calculate the frequency of the dampened oscillation. H2 (b) By what percentage does the amplitude of the...
*Please, answer all the literals and be detailed with the answer (do all the procedure and calculations) *Do it with a clear letter Homework (scattering) 1. Consider the time dependent Schrödinger equation written in the form where 0 2mo As it is well known the temporal evolution of a wave function ψ( t) known at a specific time t is uniquely determined for all future times t, > t as well as for all past times t' < t.
