Energy Level Question

Postby Anand Narayan 1G » Sun Oct 14, 2018 6:45 pm

How does the wavelength of an electron change as it jumps to a new energy level?

Think about this: Does the energy of the electron increase or decrease? How does that relate to the wavelength?

When an electron jumps from a lower energy level to a higher energy level (ex. n=1 to n=3) then energy is absorbed. Therefore, the electron gains energy since it is moving away from the nucleus. When an electron goes down to a lower energy level (returning to ground state) it emits energy. Therefore it loses energy. Since wavelength is inversely proportional to energy, when energy increases, wavelength decreases.

Thank you, Catherine for the clarification. This really helped me picture the change of an electron's wavelength in my head and give me a greater understanding.

An electron jumping to a new energy level means that it is gaining energy. When energy increases, wavelength decreases. Therefore, when an electron jumps to a new energy level, the wavelength decreases.
