Quantum mechanics part -1

The wave nature of radiation is proved by

• compton effect

• photoelectric effect

• Black body radiation

• Interference

Davisson and Germer proved wave nature of ------- particles

• Protons

• Electrons

• Neutrons

• Photons

The wave associated with a moving particles called as

• Electromagnetic wave

• Light wave

• Matter wave

• None of the above

Davisson and Germer experiment is related to

• Interference

• Polarization

• Electron diffraction

• Verification of Bohrs theory

The de Broglies wavelength of a particle is proportional to

• its mass

• its velocity

• inversely proportional to its momentum

• none

If an electron is acccelerated from rest to a velocity v by a potential V volts,then its wavelength is

The expression for momentum of a photon is

• None

when electron is accelerated by a potential V,then its debroglies wavelength

De broglies wavelength expressed in terms of K.E

The radiation exhibits particle nature is proved by

• Compton efffect

• Black body radiation

• Photoelectric effect

• All the above
