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 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 ANSWER DOWNLOAD EXAMIANS APP
