Explain particle-wave (dual) nature of matter.
Explain particle-wave (dual) nature of matter.
Optical phenomena like interference, diffraction and polarization can be explained by wave nature of light.
Photoelectric effect and Compton effect can be explained by particle nature of light.
Thus when light is in motion it behaves as wave. Its absorption and emission takes place in form of particle.
Thus light possess dual nature.

Monochromatic light with a frequency well above the cutoff frequency is incident on the emitter in a photoelectric effect apparatus. The frequency of the light is then doubled while the intensity is kept constant. How does this affect the photoelectric current?

A silver sphere of radius $1\ cm$ and work function $4.7 \ eV$ is suspended from an insulating thread in free-space. It is under continuous illumination of $200 \ nm$ wavelength light. As photoelectrons are emitted, the sphere gets charged and acquires a potential. The maximum number of photoelectrons emitted from the sphere is $A \times 10^2$ (where $1 < A < 10$ ). The value of $'Z '$ is
