d) 50.6 W/m? e) 38.0 W/m 12 At a particular moment in time and space, we measure an electromagnetic wave's electric and magnetic fields. We find the electric field E pointing West and the magnetic feld B pointing Down. What is the direction of wave propagation? a) East (b) West c) Down d) South e) Up mirror forms a real image 38.0 cm from the mirrOD the object. The mirror

(11%) Problem 1: Consider an electromagnetic wave where the electric field of an electromagnetic wave is oscillating along the z-axis and the magnetic field is oscillating along the x-axis. 8 In what directions is it possible that the wave is traveling? (Select all that apply) OThe -z dırection. Grade Su OThe -y direction. OThe -x direction. OThe +z direction. V The +y direction. Deduction OThe +x direction. Potential Submissic Attempts

A beam of light passes from air into fused quartz. Which of the following is true about the electromagnetic wave as it passes into the new medium? Material Fluorite Fused Quartz Sapphire Diamond ... Index of Refraction 1.40 1.50 1.79 2.42 A) Wavelength stays constant, frequency and speed decrease B) Speed stays constant, frequency increases, wavelength decreases C Frequency stays constant, speed decreases, wavelength increases D Frequency stays constant, speed and wavelength decrease

Chapter 35, Problem 033 Your answer is partially correct. Try again. Three electromagnetic waves travel through a certain point P along an x axis. They are polarized parallel to a y axis, with the following variations in their amplitudes. Find their resultant at P. E1 = (3.0 x 10-5 v/m) sin[(2.0 × 1014 rad/s)t] E2 = (6.0 x 10-6 V/m) sin[(2.0 x 1014 rad/s)t + 45°] Ez = (6.0 x 10-6 V/m) sin[(2.0 × 1014 rad/s)t - 45°] E = µV/m ) sin[(l 2.00 x 1014 | rad/s )t + ° (degrees)
