Particle nature and wave nature of electromagnetic waves and electrons can be shown by
Electron has small mass, deflected by the metal sheet
$X-$ ray is diffracted, reflected by thick metal sheet
Light is refracted and defracted
Photoelectricity and electron microscopy
The ratio of momenta of an electron and an $\alpha - $particle which are accelerated from rest by a potential difference of $100 V$ is
Which is not true with respect to the cathode rays
Energy of electrons can be increased by allowing them
In Millikan’s oil drop experiment, an oil drop of mass $16 \times {10^{ - 6}}kg$ is balanced by an electric field of ${10^6}V/m.$ The charge in coulomb on the drop, assuming $g = 10\,m/{s^2}$ is
An $\alpha$ particle is accelerated through a p.d of ${10^6}$ volt then $ K.E$ . of particle will be .......... $MeV$
