Q17.According to Bohr atom model, in which of the following transitions will the frequency be maximum? (1) n = 3 to n = 2 (2) n = 5 to n = 4 (3) n = 4 to n = 3 (4) n = 2 to n = 1
What This Question Tests
This question requires recalling that maximum frequency (and energy) in atomic transitions occurs for the largest energy difference between states, specifically for transitions to the ground state (n=1).
