###### Problem Details

Calculate the wavelength of the photon emitted when an electron makes a transition from n = 6 to n = 3. You can make use of the following constants:

h = 6.626×10−34J s

c = 2.998 × 108 m/s 1

m = 109 nm

Express your answer to four significant figures and include the appropriate units.

When an electronic transition from a higher energy shell to a lower energy shell takes place, a photon of light is released. The energy of the photon released during the transition is equal to the energy difference between the two shells.

Select the image to explore the simulation that demonstrates three emission series.

Click on the Lyman series in the simulation to observe the pathway of the electronic transitions from excited (or higher energy) states to the ground (or lowest energy) state. Similarly, click on the other series (Balmer and Paschen) to observe their associated electronic transitions.
