Answer :
Final answer:
The wavelength of the Lyman series transition that starts at n=4 is approximately 97.3 nm. Option C) is correct.
Explanation:
The wavelength of the Lyman series transition that starts at n=4 can be calculated using the formula:
λ = R(1/n₁² - 1/n₂²)
Where R is the Rydberg constant, which is approximately 1.097 × 10^7 m⁻¹, and n₁ and n₂ are the initial and final energy levels, respectively.
In this case, the Lyman series starts at n=1 and the transition starts at n=4. Plugging in the values, we get:
λ = (1.097 × 10^7 m⁻¹)(1/4² - 1/1²)
Simplifying the expression gives us:
λ ≈ 97.3 nm
