Calculate the wavelength of the 4⟶1 transition.

?=__________m

Step 1

Given, n = 4

The maximum number of distinct emission spectral lines (lines of different wavelengths) that can be observed from this system can be calculated as:

Step 2

The Rydberg equation for the calculation of the wavelength of an atomic element when an excited electron moves from the quantum shells is expressed as:

Step 3

Given, 4⟶1 transition

nf = 1

ni = 4

Therefore, wavelength of the spec...
