Question

According to Bohr's theory, the energy required for the transition of H-atom from n = 6 to n = 8 state is

(a) equal to the energy required for the transition from n = 5 to n = 6 state 

(b) larger than in (a) 

(c) less than in (a)

(d) equal to the energy required for the transition from n = 7 to n = 9 state

Answer 1

Correct option is (c) less than in (a)

Difference between adjacent energy levels decreases as we move outwards. 

Hence, 

\(\Delta E_{5 -7}> \Delta E_{6-8}>\Delta E_{7-9}\)

Thus 

\(\Delta E_{6-8}<\Delta E_{5 -7}\)
