Find the de Broglie wavelength of an object of mass 1 g moving with speed 0.01 m/s.

The de Broglie wavelength of a particle with mass 1 g and velocity 100 m/s is:

Calculate de Broglie wavelength of an electron (m = 9.1 xx 10^-31kg) moving with a velocity of 10^5 m//s .

The de Brogilie wavlength of an electron moving with a constant velocity is 0.367 nm. The mass of proton is 1835 times that of an electron. The de Broglie wavelength of a proton moving with the same velocity will be
