Spectroscopy Why is it generally preferable to use absorbance as a measure of absorption rather than % transmittance? Because %T cannot be measured as accurately as absorbance None of these Because absorbance is proportional to the concentration of the analyte, whereas %T is not Because %T is dependant on the power of the incident radiation Because %T cannot be measured as accurately as absorbance None of these Because absorbance is proportional to the concentration of the analyte, whereas %T is not Because %T is dependant on the power of the incident radiation ANSWER DOWNLOAD EXAMIANS APP
Spectroscopy Why must the voltage supplied to a tungsten lamp be very stable? 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 Because if it wasn't, the lamp would bum out All of these ANSWER DOWNLOAD EXAMIANS APP
Spectroscopy Beer's Law states that absorbance is proportional to the log of the concentration of the absorbing species absorbance is equal to P0 / P absorbance is proportional to both the path length and concentration of the absorbing species None of these absorbance is proportional to the log of the concentration of the absorbing species absorbance is equal to P0 / P absorbance is proportional to both the path length and concentration of the absorbing species None of these ANSWER DOWNLOAD EXAMIANS APP
