Question

According to Bohr atom model, in which of the following transitions will the frequency be maximum?

पर्याय

• n = 4 to n = 3 

• n = 2 to n = 1

• n = 5 to n = 4

• n = 3 to n = 2

Answer 1

n = 2 to n = 1

Explanation:

The transition with the highest frequency will have the biggest energy difference.

Energy difference, ΔE = 13.6`[1/"n"_1^2-1/"n"_2^2]` = hv

Energy difference is maximum if n₁ = 1 and n₂ = 2.
