Urib chiqarilgan elektronning kinetik energiyasi
What is the kinetic energy of an electron emitted by the photoelectric effect when light of wavelength 820 nm falls on a metal with work function 0.8 eV? (h = 4.1×10^-15 eV·s, c = 3.0×10^8 m/s)
To‘lqin uzunligi 820 nm bo‘lgan yorug‘lik chiqish ishi 0.8 eV bo‘lgan metallga tushganda fotoeffekt natijasida chiqqan elektronning kinetik energiyasi nimaga teng? (h = 4.1×10^-15 eV·s, c = 3.0×10^8 m/s)
