Dual nature and De broglie

Dual Nature Of Electromagnetic Radiation

Dual nature of lichen was established by

The experimental evidence for dual nature of matter come from

Which one of the following statements is not ture about de-Broglie waves ?

wave mechanical model of the atom depends upon: (a)de-Broglie concept of dual nature of electron (b)Heisenberg uncertainty principle (c)Schrodinger uncertainty principle (d)All of these

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 ?

The dual nature of light is exhibited by

Dual nature of radiation and matter

Dual nature of radiation and matter

Dual behaviour of matter proposed by de Broglie led to the discovery of electron microscope often used for the highly magnified images of biological molecules and other type of material. If the velocity of the electron in this microscope is 1.6xx10^(6) m s^(-1) . Calculate de Broglie wavelength associated with this electron.
