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.
If $5\%$ of the energy supplied to a bulb is irradiated as visible light, how many quanta are emitted per sec by a $100$ $watt$ lamp ? Assume wavelength of visible light as $5.6\times10^{-5}\, cm$.
The value of Planck's constant is
The momentum of a photon in an $X-$ ray beam of ${10^{ - 10}}$ metre wavelength is
The energy of a photon of light of wavelength $450 nm$ is
