De-broglie proposet dual nature for matter lambda = (h)/(m v) and lambda = (h)/(sqrt(2mK.E)) where m = mass, h = plancks constant. Dual nature is particle and wave nature. If an electron is accelerated by applying 100 V. The wavelength of electron is

An electrons is moving in Bohr's fourth orbits De-Broglie wavelength s lambda .What is the circumference of the fourth orbit?

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 :
