Frequency of Light Emitted in He (n=4 to n=2) Transition

To determine the frequency of light emitted in the transition from n=4 to n=2 in He, we need to apply the Rydberg formula, which relates the wavelength (λ) or frequency (ν) of light emitted or absorbed during an electronic transition to the initial (n₁) and final (n₂) energy levels of the atom.

The Rydberg formula is given by:
1/λ = R * (1/n₁² - 1/n₂²)
where λ is the wavelength, R is the Rydberg constant, and n₁ and n₂ are the initial and final energy levels, respectively.

Comparing the Transition in He to H Atom
To determine the corresponding transition in the hydrogen (H) atom, we need to find a transition that has the same frequency as the n=4 to n=2 transition in He.

Calculating Frequencies for Each Transition
1) Transition: n=3 to n=12
Using the Rydberg formula, we can calculate the frequency of light emitted in this transition in the hydrogen atom:
1/λ = R * (1/n₁² - 1/n₂²)
1/λ = R * (1/3² - 1/12²)
1/λ = R * (1/9 - 1/144)
1/λ = R * (143/1296)
λ = 1296/143R

2) Transition: n=2 to n=1
Using the Rydberg formula, we can calculate the frequency of light emitted in this transition in the hydrogen atom:
1/λ = R * (1/n₁² - 1/n₂²)
1/λ = R * (1/2² - 1/1²)
1/λ = R * (1/4 - 1/1)
1/λ = R * (3/4)
λ = 4/3R

3) Transition: n=3 to n=1
Using the Rydberg formula, we can calculate the frequency of light emitted in this transition in the hydrogen atom:
1/λ = R * (1/n₁² - 1/n₂²)
1/λ = R * (1/3² - 1/1²)
1/λ = R * (1/9 - 1/1)
1/λ = R * (8/9)
λ = 9/8R

4) Transition: n=4 to n=3
Using the Rydberg formula, we can calculate the frequency of light emitted in this transition in the hydrogen atom:
1/λ = R * (1/n₁² - 1/n₂²)
1/λ = R * (1/4² - 1/3²)
1/λ = R * (1/16 - 1/9)
1/λ = R * (9/144 - 16/144)
1/λ = R * (-7/144)
λ = -144/7R
