Dual Nature of ...

Photoelectric effect occurs only if

By Huygens’s wave theory of light, we cannot explain the phenomenon of

If the energy of an electron becomes four times, then the de Broglie wavelength of the electron will become:

Relation between wavelength of photon and electron of same energy is:

If the intensity of incident photons is increased then the photoelectric current will-

Two identical photo-electrode 1 and photo-electrode 2 receive the light of frequency f₁ and f₂ respectively of the same intensity. The photoelectric current in photo-electrode 1 and photo-electrode 2 is I₁ and I₂ respectively. If f₁ is greater than f₂, then:

According to the given statement:

a) Photoelectric effect can be explained by the wave theory of light

b) If the intensity of the incident light is increased the maximum kinetic energy of the photoelectrons also increases

Which of the following statement is correct?

If electron, α particle, proton and neutron have the same kinetic energy, then the particle which has the shortest wavelength is:

In the Davisson and Germer experiment, the velocity of electron emitted from the electron gun can be increased by

An electron of mass m and a photon have same energy E. The ratio of de-Broglie wavelengths associated with them is
