Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

A 1 MeV electron is moving in a circular orbit. Calculate its de Broglie wavelength and the radius of its orbit if it has an angular momentum of nh/2π with n = 1.

💡 Hint: Use kinetic energy relation KE = eV to find p, relating it to wavelength thereafter.

Challenge 2 Hard

Explain why the concept of standing waves is crucial for understanding electron orbits in multi-electron atoms.

💡 Hint: Consider how interference might occur among multiple waves in more complex systems.
