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. Which among the following is not used to calculate the de Broglie wavelength ?

Assertion: The de-broglie wavelength equation has significance for any microscopic or submicroscopic particles. Reason : The de-broglie wavelength is inversely proportional to the mass of the object if velocity is constant.

The de - Broglie wavelength associated with the particle of mass m moving with velocity v is
