Spectroscopy Why must the voltage supplied to a tungsten lamp be very stable? Because if it wasn't, the lamp would bum out Because the lamp will only function at a specific voltage Because amount of energy the lamp emits is proportional to the fourth power of the operating voltage All of these Because if it wasn't, the lamp would bum out Because the lamp will only function at a specific voltage Because amount of energy the lamp emits is proportional to the fourth power of the operating voltage All of these ANSWER DOWNLOAD EXAMIANS APP
Spectroscopy Why is it generally preferable to use absorbance as a measure of absorption rather than % transmittance? None of these Because %T cannot be measured as accurately as absorbance 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 None of these Because %T cannot be measured as accurately as absorbance 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 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 absence of broad spectrum of wavelenth light is faster today that it used to be the Fourier Transfer Algorithm allows us to scan all frequencies at once None of these absence of broad spectrum of wavelenth light is faster today that it used to be the Fourier Transfer Algorithm allows us to scan all frequencies at once None of these ANSWER DOWNLOAD EXAMIANS APP
Spectroscopy Beer's Law states that None of these absorbance is equal to P0 / P absorbance is proportional to both the path length and concentration of the absorbing species absorbance is proportional to the log of the concentration of the absorbing species None of these absorbance is equal to P0 / P absorbance is proportional to both the path length and concentration of the absorbing species absorbance is proportional to the log of the concentration of the absorbing species ANSWER DOWNLOAD EXAMIANS APP
