Threshold wavelength for photoelectric emission from a metal surface is 3800Å , Utraviolet light of wave-length 2600Å is incident on the metal surface. maximum kinetic energy of emitted photoelectron. (h = 6.63 xx 10^(-27) " erg.s")

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) ]

The threshold wavelength for photoelectric emission in tungsten is 2300 Å. What wavelength of light must be used to eject electrons with a maximum energy of 1.5 eV?

The threshold wavelength of tungsten is 2300 Å. If ultra voilet light of wavelength 1800 Å is incident on it, then the maximum kinetic energy of photoelectrons would be

The photoelectric threshold wavelength for a metal is 10,000 Å . When light of wavelength 5461 Å is incident on it, the retarding potential in Millikan's experiment is 1.02 V. Calculate the value of Planck's constant.
