Unpolarized light, such as sunlight, with intensity 1200 W/sq*m is passed through a single polarizing filter. (a) What is the average intensity of the light after it has passed through this first filter? A second filter is now added to the path of this sunlight. The axis of this filter is turned at an angle of 37 degrees to the direction of the first polarizing filter. (b) What now will be the Intensity of the light which has passed through both filters ?

A solar sail 32.5 m2 in area and made of an absorptive material is orbiting the Sun in space. The Sun light normally incident on the solar sail exerts a radiation pressure of 3.22E-6 N/m2 on it. If the material is replaced with a reflective material that can complete reflect the Sun light, what will the radiation pressure become (in N/m2)?

The electric component of a beam of polarized light is Ey = (5.08 V/m) sin[(1.10 × 10° m-4)z + wt). (a) Write an expression for the magnetic field component of the wave, including a value for w.

The average intensity of light emerging from a polarizing sheet is 0.789 W/m2, and that of the horizontally polarized light incident on the sheet is 0.865 W/m2. Determine the angle that the transmission axis of the polarizing sheet makes with the horizontal.

Chapter 27: Problem 6: Unpolarized light of intensity I0 = 950 W/m² is incident upon two polarizers. The first has its polarizing axis vertical, and the axis of the second is rotated θ = 65° from the vertical. Randomized Variables I0 = 950 W/m² θ = 65°   Part (a) What is the intensity of the light after it passes through the first polarizer in W/m²?  Part (b) What is the intensity of the light after it passes through the second polarizer in W/m²?

We want to rotate the direction of polarization of a beam of polarized light through 90° by sending the beam through one or more polarizing sheets. (a) What is the minimum number of sheets required? (b) What is the minimum number of sheets required if the transmitted intensity is to be more than 83% of the original intensity?

Unpolarized light passes through three polarizing filters. The first filter has its transmission axis parallel to the z direction, the second has its transmission axis at an angle of 30.0° from the z direction, and the third has its transmission axis at an angle of 60.0° from the z direction. If the light that emerges from the third filter has an intensity of 587.0 W/m², what is the original intensity of the light? (Assume both angles are measured in the same direction from the +z axis.)
