Spectroscopy Why is it generally preferable to use absorbance as a measure of absorption rather than % transmittance? None of these Because %T is dependant on the power of the incident radiation Because absorbance is proportional to the concentration of the analyte, whereas %T is not Because %T cannot be measured as accurately as absorbance None of these Because %T is dependant on the power of the incident radiation Because absorbance is proportional to the concentration of the analyte, whereas %T is not Because %T cannot be measured as accurately as absorbance ANSWER DOWNLOAD EXAMIANS APP

Spectroscopy Why must the voltage supplied to a tungsten lamp be very stable? Because if it wasn't, the lamp would bum out Because amount of energy the lamp emits is proportional to the fourth power of the operating voltage Because the lamp will only function at a specific voltage All of these Because if it wasn't, the lamp would bum out Because amount of energy the lamp emits is proportional to the fourth power of the operating voltage Because the lamp will only function at a specific voltage All of these ANSWER DOWNLOAD EXAMIANS APP
