The de Broglie equation relates the wavelength of a particle to its velocity and mass, and it is particularly important in understanding the properties of subatomic particles. This page will present you with a variety of questions demonstrating the application of the de Broglie relationship. When you press "New Problem" a question will appear. Determine the value of the answer, enter it in the answer cell and press "Check answer".
Results will appear along with running totals. Pressing "Show Answer" will cause the solution to appear and you will no longer be able to submit an answer for that problem. A few hints:

All wavelengths must be in meters.

Numbers in scientific notation must be entered using "e". Thus 2*10^{2} is entered as 2e2.
