The diffraction phenomenon can be observed whenever the wavelength is comparable in magnitude to the size of the slit opening. To be “diffracted,” how fast must a person weighing 84 kg move through a door 1 m wide?

Step 1

For diffraction to occur, wavelength *λ* must be comparable to the size of slit opening. Therefore, *λ* = 1m. If *v* is the velocity of the person, *m* is the mass, then, from De-Broglie equation,

Step 2
