Changing the Electron Pattern

Let us see how this pattern changes with the energy of the electron. Keeping other variables fixed try at least four different energies and measure the distance between consecutive dark areas on the screen.

Address the following questions:

How does the distance between dark areas change as the energy increases?

For the plastic waves look at how the distance between zeros changed with wavelength. Use that information to describe below how the electron’s wavelength changes as the energy increases.
