When performing an addition or subtraction calculation, significant figures in the calculated result are dictated by the of the measured numbers. The calculated result should have the measured number in the calculation with the fewest

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?
