Also, let the center disk be rotated on a the common axis with angular speed o. Show that if unpolarized light is incident on the left disk with an intensity Imax, the intensity of the beam emerging from the right disk is 1 I =Ima (1- cos 4ot) 16 This means that the intensity of the emerging beam is modulated at a rate four timés the rate of rotation of the center disk. Hint: Use the trig. identities cos? 0=(1+ cos20)/2 and sin? 0=(1- cos20)/2

The helium-neon laser usually used in classrooms typically provides an intensity of about 14 What are the rms electric and magnetic fields 1m/wm for such a beam? Hint: Poynting vector We know that electric and magnetic fields store energy, and so as EM wave propagates, it carries energy. The rate of energy flow, in watts per square meter, can be shown to be: S = ¹ EX B Ho S is the Poynting vector. It points in the direction the energy is propagating.

Light that passes through a series of three polarizing filters emerges from the third filter horizontally polarized with an intensity of 280 W/m22. 1 If the polarization angle between the filters increases by 15∘∘ from one filter to the next, find the intensity of the incident beam of light, assuming it is initially unpolarized.

..54 Dispersion in a window pane. In gle e Fig. 33-54, a beam of white light is incident at an- 50° on a common window pane (shown in cross section). For the pane's type of glass, the index of refraction for visible light ranges from 1.524 at the blue end of the spectrum to 1.509 at the red end. The two sides of the pane are paral- lel. What is the angular spread of the colors in the beam (a) when the light enters the pane and (b) when it emerges from the opposite side? (Hint: When you look at an object through a window pane, are the colors the light from the object dispersed as shown in, say, Fig. 33-20?) = Ꮎ Figure 33-54 Problem 54.
