Question
A) which represents orientation or electric & magnetic field components? B) speed of the wave, if B is in 5.0nT C) effect of ainesr polarizing filter on the wave? 5. If an EM wave is traveling out of the page and is vertically-polarized, etic fi netic field (a) which of the following represents the orientation of the electric and mag components? (b) What is the speed of the wave, if B is 5.0nT? (c) What would the effect of a linear polarizing filter (placed at 45 degree to the polarization direction of the wave) be on the wave?Explanation / Answer
1) A "vertically polarized" electromagnetic wave of wavelength ? has its electric field vector E (red) oscillating in the vertical direction. The magnetic field B (or H) is always at right angles to it (blue). The image on the right is the correct answer
2) In a vacuum, electromagnetic waves travel at a constant speed (the speed of light), usually represented by the letter c. The speed changes slightly due to the medium the wave is traveling through
3) That filter would allow passage of only 45 degree plane polarized light, since the beam of interest is vertically polarized it would not pass
