Spectroscopy Why must the voltage supplied to a tungsten lamp be very stable? Because if it wasn't, the lamp would bum out All of these 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 Because if it wasn't, the lamp would bum out All of these 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 ANSWER DOWNLOAD EXAMIANS APP
Spectroscopy Why is it generally preferable to use absorbance as a measure of absorption rather than % transmittance? Because %T is dependant on the power of the incident radiation Because %T cannot be measured as accurately as absorbance Because absorbance is proportional to the concentration of the analyte, whereas %T is not None of these Because %T is dependant on the power of the incident radiation Because %T cannot be measured as accurately as absorbance Because absorbance is proportional to the concentration of the analyte, whereas %T is not None of these ANSWER DOWNLOAD EXAMIANS APP
