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 absence of broad spectrum of wavelenth the Fourier Transfer Algorithm allows us to scan all frequencies at once None of these light is faster today that it used to be absence of broad spectrum of wavelenth the Fourier Transfer Algorithm allows us to scan all frequencies at once 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 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 Because if it wasn't, the lamp would bum out Because the lamp will only function at a specific voltage ANSWER DOWNLOAD EXAMIANS APP
