An electron in the hydrogen atom makes a transition from an energy state of principal quantum number nt to the n = 1 state. If the photon emitted has a wavelength of 95 nm, what is the value of nt?

check_circleExpert Solution
Step 1

The relation of wavelength (λ) with the principle quantum number of the initial (ni) and the final energy levels (nf) for a given transition is given by expression (1). In this expression R represents Rydberg constant.

Step 2

The relation between m and nm units is,

1 nm = 10-9 m

Hence, the given value of wavelength 95 nm is equal to 95 × 10-9 m....
