Spectroscopy Why must the voltage supplied to a tungsten lamp be very stable? Because the lamp will only function at a specific voltage All of these Because amount of energy the lamp emits is proportional to the fourth power of the operating voltage Because if it wasn't, the lamp would bum out Because the lamp will only function at a specific voltage All of these Because amount of energy the lamp emits is proportional to the fourth power of the operating voltage Because if it wasn't, the lamp would bum out ANSWER DOWNLOAD EXAMIANS APP
Spectroscopy Which of the following relationships between absorbance and %transmittance is incorrect? A = 2 - log10 %T All are correct A = log10 1 / T A = log10 100 / %T A = 2 - log10 %T All are correct A = log10 1 / T A = log10 100 / %T 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 None of these light is faster today that it used to be the Fourier Transfer Algorithm allows us to scan all frequencies at once absence of broad spectrum of wavelenth None of these light is faster today that it used to be the Fourier Transfer Algorithm allows us to scan all frequencies at once absence of broad spectrum of wavelenth ANSWER DOWNLOAD EXAMIANS APP
