Solution: Calculate the wavelength of light emitted when the electron in the hydrogen atom undergoes a transition from level n4 to n3?

Problem

Calculate the wavelength of light emitted when the electron in the hydrogen atom undergoes a transition from level n4 to n3?

Solution

The wavelength of the light emitted when the electron in the hydrogen atom undergoes a transition from level n = 4 to n = 3 can be calculated using the speed of light: 


c = λ·v

c = speed of light = 3.0x108 m/s
λ = wavelength, in m


Since we don’t have a frequency, we can rearrange the equation:


v = cλ

Recall the energy equation:
