Question

Calculate the wavelength of the spectral line in lyman series corresponding to n = 3

Answer 1

Answer:

Lyman series is jumping from given orbital to no. 1 orbital. Here given orbital=3

Answer 2

Answer:

For Lyman series n1 = 1

Given that n2 = 3

According to Rydberg equation:

1λ = R (1n12 − 1n22)1λ = 109677(1(1)2 − 1(3)2)1λ= 109677(89)λ = 1.02 × 10−5 cm = 102.6 nm
