Problem an electron with a speed of 21 x 106 ms collides, Ask an Expert

Academics

Problem: An electron with a speed of 2.1 x 106 m/s collides with a hydrogen atom, exciting the atom to the highest possible energy level. The atom then undergoes a quantum jump with change in change in n = 1.

Part A- What is the wavelength of the photon emitted in the quantum jump?

I don't just need an answer, work and explanations/walkthrough would be much appreciated! Thank you.
