Very Large Masses

While wave behavior is exhibited by electrons, pions, neutrons and protons; we do not observe similar behavior for large objects such as gnats or humans. As an example, we will consider why diffraction doesn’t cause a gnat to look like several gnats as it flies through window blinds. Start with a gnat whose mass is .001 kg, and speed is 0.10 m/s.

What is the gnat’s momentum?

What is the gnat’s de Broglie wavelength?

Approximately what would the spacing between the window blinds have to be for the gnat to create a pattern as it flew through? Why?

Is it necessary for a gnat to worry about creating a pattern as it flies through the blinds? Why?

How would a human being’s de Broglie wavelength compare to that of a gnat? Why?
