We can use the Rydberg-Ritz formula to calculate the wavelength predicted for the transition from n=3 to n=2.

1/λ = RS1U1B1(1/2^2 - 1/3^2)

Substituting the given value for the constant RS1U1B1, we get:

1/λ = 10.96776 µm S1U1P1-1 S1S1P0 (1/4 - 1/9)

Simplifying, we get:

1/λ = 10.96776 µm S1U1P1-1 S1S1P0 (5/36)

1/λ = 1.83047 x 10^7 cm^-1

λ = 545.7 nm

Therefore, the closest choice to this predicted wavelength is A) 656 nm.
