Light intensity is measured in foot-candles or lux and represents the amount of light evident from a source. on an average sunlit day, the intensity measure is 32,000 to 100,000 lux. a bright office is lit at about 400 lux. the intensity measure of an electronic device is given by the function:
i = 36log [a/a0]
where a is the measured amplitude of the light intensity and a0 is the measured intensity of moonlight. although i varies with the brightness of different images displayed, if the intensity measure of a computer display is 60, how many times brighter is the computer display than moonlight? carry out your calculations four decimal places and round your answer to two decimal places.
