Question

Which of the following transition in a hydrogen atom emit photon of the highest frequency:

विकल्प

• n = 1 to n = 2

• n = 2 to n = 1

• n = 2 to n = 6

• n = 6 to n = 2

Answer 1

n = 1 to n = 2

Explanation:

From E = E₂ – E₁ = `- 13.6/2^2`

= `((-13.6)/1^2)`

= `- 3.4 + 13.6`

= 10.2 ev

This value is the maximum, so v is the maximum.
