1. A 100 Watt incandescent bulb is about 5.0% efficient at converting electrical energy into radiantenergy (i.e. it produces 5.0 W of light energy). Assume the bulb projects light equally in alldirections and produceslight that is randomlyUnpolarizedlight source8.0 mpolarized (in other wordsthe source is isotropic andvery small distance between filters(not to scale)unpolarized). A pair of30°polarizing filters is used toObserverexamine the light at aposition 8.0 meters awayFirst filter has electricfield transmission axisalligned vertically.from the bulb.Second filter/analyzer has axisat 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, andthe second analyzing filter is placed immediately behind the first and is aligned at a 30degree angle from the vertical, what will be the intensity of light exiting the pair of filters toa nearby observer?

Given light energy produced by lamp is P=5W R=8.0m Φ=30⁰
