Film studios, photographers, and the lighting industry usually measure light intensity in foot-candles - historically, the amount of light one candle generates on a surface one foot away. Light intensity / (in foot- candles) is directly proportional to candlepower P (which measures how much light is generated by a light source) and inversely proportional to the square of the distance, d, from the light source. The relationship is the inverse square law where I is measured in foot-candles, P in candlepower, and d in feet. Surgeons use a lamp that supplies 4000 foot-candles when suspended 3 feet above the operating surface. a. What candlepower would the source have to provide? candlepower b. Lighting engineers assume that surgery requires somewhere in the range of 2000 to 5000 foot-candles. How high above the operating surface would you hang the lamp to give 4500 foot-candles?
