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

Spectroscopy Why must the voltage supplied to a tungsten lamp be very stable? All of these Because the lamp will only function at a specific voltage 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 All of these Because the lamp will only function at a specific voltage 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 ANSWER DOWNLOAD EXAMIANS APP

Spectroscopy In the past, IR spectra had to be aquired one wavelength at a time, which took a long time. Today quick spectra is due to the the Fourier Transfer Algorithm allows us to scan all frequencies at once light is faster today that it used to be None of these absence of broad spectrum of wavelenth the Fourier Transfer Algorithm allows us to scan all frequencies at once light is faster today that it used to be None of these absence of broad spectrum of wavelenth ANSWER DOWNLOAD EXAMIANS APP
