Answer:
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
