Solution: Calculate the wavelength of light emitted when the following transition occur in the hydrogen atom. n = 4 → n = 3What type of electromagnetic radiation is emitted?

Solution: Calculate the wavelength of light emitted when the following transition occur in the hydrogen atom. n = 4 → n = 3What type of electromagnetic radiation is emitted?

Problem

Calculate the wavelength of light emitted when the following transition occur in the hydrogen atom. 

n = 4 → n = 3

What type of electromagnetic radiation is emitted?

Solution

Recall that the energy change between two energy levels in an H atom can be calculated as:

where

ΔE is the energy involved in K; -2.178x10-18 J is the Rydberg constant for this transition; and n are the transitions
