Question

Constants Part A - Practice Problem: and has a In this example we will calculate the electric and magnetic fields of a carbon dioxide laser. The laser erits a sinusoidal electromagnetic wave that travels in vacuum in the direction. The wavelength is 10.6 um, and the field is along the axis, with a maximum magnitude of 1.5 MV/m. Find the equations for the magnitudes of vectors E and B as functions of time and position. What is E. for the electric field of an electromagnetic wave that has a magnetic field that oscillates with a frequency of 382 GH maximum strength of 1.25 x 101 T? Express your answer in volts per meter to three significant figures. 0 AED o o ? Submit Request Answer Part B - Practice Problem: What is w for the electric field of an electromagnetic wave that has a magnetic field that oscillates with a frequency of 38.2 GHz and has a maximum strength of 1.25 x 10 * T? Express your answer in radians per second to three significant figures.

solve part A,B,C

Answer 1

so ginen data Part A B = 1-25x104T we know that, E=CB E = 3x108x1-250107 E = 37500 um TE= 375x10² um part-B given that frequency, f = 38.2 GHZ f=38.2 x 109 HI angular prequency - 211f = 27x38.24109 w = 2.400)76x10" rod sec

c) propogation vector es related to wavelength by the relation k=RT 2.4oo176x10 3x108 K-800.05 bodlm [ k=800 rod/m.
