Please help with questions below. Please provide detail.

1) Define the deBroglie wavelength and briefly outline de Broglie's theory of matter waves

2) If my mass is 54.4 kg, calculate my own wavelength when I am am running at 4.0 m/s. Why is my wave nature not important as I run through the door of a physics classroom?

3) Outline or define:

a) Compton's Findings

b) mass equivalence

c) Pair production
