Dual nature of matter was proposed by de Broglie in 1923, it was experimentally verified by Davisson and Germer by diffraction experiment. Wave haracter of matter has significance only for microscopic particles. De Broglie wavelength `(lambda)` can be calculated using the relation, `(lambda) = (h)/(m v)`
where 'm' and 'v' are the mass and velocity of the particle.
The wavelength of matter waves associated with a body of mass 1000g moving with a velocity of 100m/sec is :
