Qizil chegara chastotasidan ikki marta katta
In a photoelectric experiment, electrons are emitted when the light's frequency exceeds f 0. If light of frequency 2f 0 shines on the metal, what is the maximum kinetic energy of the photoelectrons? (h is Planck's constant.)
Fotoeffekt tajribasida yorug‘lik chastotasi f 0 dan oshganda elektronlar chiqadi. Agar metallga 2f 0 chastotali yorug‘lik tushirilsa, fotoelektronlarning eng katta kinetik energiyasi nimaga teng? (h — Plank doimiysi.)
