Question

A macroscopic particle of mass 100 g and moving at a velocity of 100 cm s⁻¹ will have a de Broglie wavelength of

Answer 1

of mass 100 gm and moving at a velocity of 100 cm s –1 will have a wavelength ... de-Broglie wavelength of a tennis ball of mass 60 g moving with a velocity

Answer 2

de broglie wavelength =h/mv

h=6.626×10^-34kgm^2s^-1

m=100g=100×10^-3 kg

v=100×10^-2 ms^-1

wave length

=6.626×10^-34/100×10^-3×100×10^-2

=6.626×10^-49m.
