DUAL NATURE OF RADIATION AND MATTER Set 1

If a voltage applied to an -ray tube is increased to 1.5 times the minimum wavelength of an -ray continuous spectrum shifts by The initial voltage applied to the tube is

Dual nature of radiation is shown by

A photon will have less energy, if its

The momentum of a charged particle moving in a perpendicular magnetic field depends on

The energy of a photon of green light of wavelength 50000 is

The wavelength of de-Broglie wave is 2µm, then its momentum is (h = 6.63 x 10⁻³â´ Js)

When a monochromatic point source of light is at a distance 0.2 m from a photoelectric cell, the saturation current and cut-off voltage are 12.0 mA and 0.5 V. If the same source is placed 0.4 m away from the photoelectric cell, then the saturation current and the stopping potential respectively are

In Millikan's oil drop experiment, a charged drop falls with terminal velocity if an electric field is applied in vertically upward direction then it starts moving in upward direction with terminal velocity if magnitude of electric field is decreased to then terminal velocity will becomes

In Millikan's oil drop experiment, a charged drop of mass kg is stationary between the plates. The distance between the plates 0.9 cm and potential difference between the plates is 2000 V. The number of electrons on the oil drop is

-rays are produced due to
