A 100 Watt incandescent bulb is about 5.0% efficient at converting electrical energy into radiant energy (i.e. it produces 5.0 W of light energy). Assume the bulb projects light equally in all directions and produces light that is randomly Unpolarized light source 8.0 m polarized (in other words the source is isotropic and very small distance between filters (not to scale) unpolarized). A pair of 30 polarizing filters is used to Observer examine the light at a First filter has electric field transmission axis alligned vertically. position 8.0 meters away from the bulb. Second filter/analyzer has axis at 30° angle relative to the first. (A) What is the intensity of light at the position of the filters just before it enters the first filter? (B) If the first filter faces the lamp and aligned and has a vertically aligned transmission axis, and the second analyzing filter is placed immediately behind the first and is aligned at a 30 degree angle from the vertical, what will be the intensity of light exiting the pair of filters to a nearby observer?

The axes of a polarizer and an analyzer are oriented at 30° to each other. (a) If unpolarized light of intensity I is incident on them, what is the intensity of the transmitted light? (b) Polarized light of intensity I is incident on this polarizer-analyzer system. If the amplitude of the light makes an angle of 30° with the axis of the polarizer, what is the intensity of the transmitted light?

Unpolarized light passes through two ideal polarizers in turn with polarization axes at 43.9° to each other. What is the fraction of the incident light intensity that is transmitted?

An unpolarized beam of light with an intensity of 5000 W/m2 is incident on two ideal polarizing sheets. If the emerging light has an intensity 0.200 times the original intensity of the incident beam, what is the angle between the two polarizers?

Vertically polarized light of intensity lo is incident on a polarizer whose transmission axis is at an angle of 70° with the vertical. If the intensity of the transmitted light is measured to be 0.34W/m², the intensity lo of the incident light is O 1.71 W/m2 O 0.99 W/m² O 0.43 W/m2 O 2.91 W/m²

Yellow light with wavelength 600nm propagates in the +x direction. The wave is linearly polarized along the ±y direction. a) Draw a labeled snapshot mode picture of what the electric and magnetic fields look like. Use vector representation. b) Determine the frequency of oscillation of the electric field vector for the yellow light. Is the magnitude of this frequency very large or very small?

Unpolarized light with intensity Io is incident on a series of polarizing sheets. The first sheet has itstransmission axis oriented at 90°. A second polarizer has its transmission axis oriented at 60° .Determine the fraction of light intensity exiting the second sheet?
