Suppose you conducted the hydrogen emission experiment, and you observed four different colored light beams, but they were extremely dim.

Question

Would you conclude the powersupply was faulty or would you conclude that the tube did not contain enough hydrogenatoms? Explain your reasoning.

Answer 1

Refer to my previous answer to a question you asked about the same phenomenon. In this case, since you observe ALL FOUR spectral lines, this indicates that the energy source (power supply) is sufficient. The observation that they are all very dim suggests that the sample of hydrogen is in limited supply.
