Dual nature of matter was proposed by de...

Dual nature of matter was proposed by de Broglie in 1923, it was experimentally verified by Davisson and Germer by diffraction experiment. Wave character of amtter has significance only for microscopic partiles. De Broglie wavelength or wavelength of matter wave can be calculated using the following relation:
`lamda=(h)/(mv)`
Where, 'm' and 'v' are te mass and velocity of the particle. de Broglie hypothesis suggested that electron waves were being diffracted by the target, much as X-rays are diffracted by planes of atoms in the crystals.
Q. Planck's constant has same dimension as that of:

A

C

power

D
