Consider the transition from the energy levels n = 3 to n = 5. what is the wavelength associated with this transition, in nm?

wavelength is 1301.8 nm

Explanation:

Given data

energy levels n = 3 to n = 5

to find out

What is the wavelength

solution

we know wavelength formula that is given below

1/wavelength = RH(1/n1² - 1/n2²)

here we know RH value is  10973731.6 m^(-1)

so

wavelength = 1 / RH(1/n1² - 1/n2²)

wavelength = 1 / 10973731.6 (1/3² - 1/5²)

wavelength = 1.3018 ×10^-6 m

wavelength is 1301.8 nm
