For this problem you will need to consult the response curve below. Consider that you are using a homebuilt UV/VIS absorbance spectrometer. You utilize a 500nm LED with a 5nm bandwidth. The output of this LED is 10mW of collimated light. The LED is positioned 1cm from a 1cm quartz cuvette (=1.50 at 500nm ). A 1mm active area silicon photodiode (S6931-01) is positioned 1cm from the cuvette. You can assume that the total transmittance (accounting for ALL reflective losses) through the cuvette filled with a non-absorbing blank solution is 90% based on your work on the first problem set. What is the current measured at the detector when the cuvette contains 1.0M of an absorbing solution (=20,000M1cm 1)? Spectral response Wavelength (nm)
