🤓 Based on our data, we think this question is relevant for Professor Bojan's class at PSU.

Solution: What wavelength of light will be required to remove an electron from the n = 3 shell of a hydrogen atom?

Problem

What wavelength of light will be required to remove an electron from the n = 3 shell of a hydrogen atom?

Solution

The wavelength of the light required to remove the electron from the n = 3 shell can be calculated using the speed of light:

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

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

Recall the energy equation:
