Per NCERT eqn 2.9, the Rydberg formula for all spectral lines in hydrogen uses a constant value of approximately which figure?
A3 × 10⁸ m s⁻¹
B6.626 × 10⁻³⁴ J s
C109,677 cm⁻¹
D109,677 m⁻¹
Answer & Solution
Correct answer: C. 109,677 cm⁻¹
Per NCERT eqn 2.9, Rydberg constant = 109,677 cm⁻¹. Other figures are h and c.
