Using the Rydberg Energy Equation of 1/λ = R * Z² * (1/n₂² - 1/n₁²)
this is where λ is the wavelength, z is atomic number, n₁ is the initial energy level, n₂ the final energy level and R is the Rydberg constant with a value of ≈ 1.0973 * 10^7 1/m.
If we plug all the given numbers in the the equation we are left with an unknown of n₂, solve for n₂ and your answer will be 2.00
