Question

A hydrogen atom in its ground state absorbs 10.2 eV of energy. The orbital angular momentum is increased by-

• A. 1.05 × 10^–34 J-sec
• B. 3.16 × 10^–34 J-sec
• C. 2.11 × 10^–34 J-sec
• D. 4.22 × 10^–34J-sec

Answer 1

Answer: (A)

1.05 × 10^–34 J-sec

Answer 2

DJ = J₂ – J₁ = $\frac{h}{2\pi}(2–1)$
