Photoelectric effect and diffraction
Wavelength of a $1 \;keV$ photon is $1.24 \times {10^{ - 9}}\;m$. What is the frequency of $1 \;MeV$ photon
The photo-electrons emitted from a surface of sodium metal are such that
By suitable example show that particle or wave nature depend on type of experiment.
Momentum of a photon of wavelength $\lambda$ is
Two monochromatic beams $A$ and $B$ of equal intensity $I$, hit a screen. The number of photons hitting the screen by beam $A $ is twice that by beam $ B$. Then what inference can you make about their frequencies ?
