Chiqish ishini topish
Ultraviolet light of wavelength 310 nm strikes an unknown metal in vacuum, ejecting electrons with kinetic energy 1.5 eV. What is the work function of the metal? (hc = 1240 eV·nm)
To‘lqin uzunligi 310 nm bo‘lgan ultrabinafsha nurlar vakuumda noma’lum metallga tushib, kinetik energiyasi 1.5 eV bo‘lgan elektronlarni urib chiqaradi. Metallning chiqish ishi nimaga teng? (hc = 1240 eV·nm)
