Which of the following phenomena establishes the wave nature of particles?
1 Millikan oil drop experiment
2 Davission-Germer experiment
3 Sterm-Gerlach experiment
4 Franck-Hertz experiment
Explanation:
: Davission-Germer experiment establishes the wave nature of particles through electron diffraction. A low voltage power supply was used to heat an electron gun with a tungsten filament coated with barium oxide. Davisson Germer experiment showed that electron beams can undergo diffraction when passed through atomic crystal. This shown the wave nature of electrons as waves cane exhibit interference and diffraction.

Which one of the following property of light does not support wave theory of light?
1 Light obeys laws of reflection and refraction
2 Light waves get polarised
3 Light shows photoelectric effect
4 Light shows interference
Explanation:
: Wave theory \(\rightarrow\) law of refractive as refractive polarization and interference. Photoelectric effect supports \(\rightarrow\) Particle theory

In the phenomena of diffraction of light, when blue light is used in the experiment in spite of red light, then
1 Fringes will become narrower
2 Fringes will become broader
3 No change in fringe width
4 none of these
Explanation:
: Wavelength of blue light is less than the wavelength of red light, therefore fringes will become narrower. \(\lambda_{\text {blue }}<\lambda_{\text {red }}\)

A wave front is an imaginary surface where:
1 phase is same for all points
2 phase changes at a constant rate at all points along the surface
3 constant phase difference continuously changes between the points
4 phase changes all over the surface
Explanation:
: A wave front is an imaginary surface where all particles lying on this vibrate in the same phase.
