The work function of sodium metal is `4.41xx10^(-19)J`. If photons of wavelength 300 nm are incident on the metal, the kinetic energy of the ejected electrons will be `(h=6.63xx10^(34)Js,c=3xx10^(8)` m/s ______ `xx10^(-21)`

Light of wavelength 500 nm is incident on a metal with work functin 2.28 eV.The de-Broglie wavelength of the emitted electron is :[ h=6.6xx10^(-34Js) and c=3xx10^(8)m//s ]

If the work function of a certain metal is 3.2xx10^(-19)J and is it illuminated with light of frequency 8xx10^(14) Hz, the maximum kinetic energy of photo electrons would be (h=6.6xx10^(-34)Js)

The work function of a metal is 3.3 xx 10^-19 J . The maximum wavelength of the photons required to eject electron from the metal is :

For photoelectric emission, threshold wavelength of a metal is 2460 Å . If ultraviolet light of wavelength 1810 Å be incident on the metal, what will be the maximum kinetic energy of the emitted electrons? [Planck's constant = 6.62xx10^(-34) J.s , velocity of light in veccuum = 3xx10^(8) m.s^(-1) ]
