Only of the intensity of a polarized light wave passes through a polarizing filter. What is the angle between the electric field and the axis of the filter?
Angle between field of force and also the axis of the filter,
Horizontal polarizing occurs when light reflects off horizontal surfaces like the road, water, or snow. A vertically oriented polarized filter will reduce glare while still allowing many light to experience. A polarized filter on your camera can assist decrease glare. The identical principle applies to polarized sunglasses.
We may find angle by staring the subsequent relation :
We are now calculating for
(Where is )
Consider current passing through a resistor of radius , length , and resistance .
a. Determine the electric and magnetic fields at the surface of the resistor. Assume that the electric field is uniform throughout, including at the surface.
b. Determine the strength and direction of the Poynting vector at the surface of the resistor.
c. Show that the flux of the Poynting vector (i.e., the integral of ) over the surface of the resistor is . Then give an interpretation of this result.
