Question

The de broglie wavelength associated with a ball of mass 200 g and moving at a speed of 5m/h is of the order of

Answer 1

Answer:

wavelength = 6.626*10^-34/0.2*(5/60)

wavelength = 6.626*10^-34*12/0.2

wavelength = 79.512*10^-34/0.2

wavelength = 397.56*10^-34

wavelength = 3.97*10^ -32
