Question

A) which represents orientation and magnetic field? B) speed? C) effect of polarizing?
Answering number 6 is a bonus:) please and thank you. If an EM wave is traveling out of the page and is vertically-polarized, which of the following represents the orientation of the electric and magnetic field components? What is the speed of the wave, if B is 5.0nT? What would the effect of a linear polarizing filter (placed at 45 degree to the polarization direction of the wave) be on the wave? Captain Kirk gets on a space ship and travels at Warp-10 (10 times the speed of light) to the Klingon home-world. After 10 days of traveling, he reaches the distant planet and communicates with Earth, to find out that 10 days have passed on Earth as well. Describe two things wrong with the scenario and why.

Explanation / Answer

A) NONE IS POSSIBLE as direction of EM WAVE is given by E x B (CROSS PRODUCT) so 1st and 3rd giving into the page and 2nd is not at all possible because E and B are not perpendicular

b) c = E/B

so, E = 1.5 N/C
