Question

When an electron of a hydrogen atom travels from n = 4 to n = 2, a photon of energy 4.165 × 10-19 joules is released. Calculate the wavelength associated with this radiation.

Answer 1

Step-by-step explanation:

please delete this it was a mistake

Answer 2

4.77 × 10-7 meters

Step-by-step explanation:

Energy of photon, E = hν

Frequency of photon,

Thus, energy of photon,

Therefore, 4.165 × 10-19 joules =

λ =

λ =

λ = 4.77 × 10-7 meters

The frequency of a photon having energy of 4.165 × 10-34 joules is 4.77 × 10-7 meters.
