(a) Figure 33-27 shows light reaching a polarizing sheet whose

polarizing direction is parallel to a y axis. We shall rotate the sheet 40°

clockwise about the light’s indicated line of travel. During this

rotation, does the fraction of the initial light intensity passed by the

sheet increase, decrease, or remain the same if the light is (a) initially

unpolarized, (b) initially polarized parallel to the x axis, and (c)

initially polarized parallel to the y axis?

If the magnetic field of a light wave oscillates parallel to a y axis and is given by By = Bm sin(k z − ωt), (a) in what direction does the wave travel and (b) parallel to which axis does

the associated electric field oscillate?

Draw the reflection rays for the incident rays shown below.include the normal at each point where the incident rays strikes the surface of the mirrors

Light scattered from blue sky is strongly polarized because of the nature of the scattering

process described in Section 33.6. But light scattered from white clouds is usually not polarized.
