Question

A line in Lyman series of hydrogen atom has a wavelength of 1.03 × 10⁻⁷ m. What is the initial energy level of the electron?

Answer 1

.........................................it may be 3479

Answer 2

Answer:

initial energy level of the electron is 3

Explanation:

the formula for Lyman series is

1 / λ = R { 1 / P² - 1 / n² }

1 / 1.03 × 10⁻⁷ = 1.09 × 10⁷ { 1 / (1²) - 1 / n² }

1 / 1.03 × 10⁻⁷ = 1.09 × 10⁷ { 1 - 1 / n² }

1 / 1.1227 = 1 - 1 / n²

1 - 0.89  =  1 / n²

n²  = 1 / 0.11

n²  =  9

n = 3
