Expert Answer

Step 1

The Rydberg’s formula for an electron changing its energy level by emitting a photon of a particular wavelength is shown as follows:

1 = R is the wavelength of light emitted. Ry is Rydberg's constant is equal to 1.097x 10' m1. n and n are the final and initial level of an electron respectively

Step 2

The above formula can be modified for convenience because the original formula doesn’t consider energy change directly.

Therefore, the modified Rydberg’s formula for an electron changing its energy level by emitting a photon of a particular wavelength is shown as follows:
