APAKAH MAKSUD PHOTOEMISSION dalam CORSICA?
Kesan fotoelektrik
Kesan fotoelektrik adalah pemerhatian bahawa banyak logam memancarkan elektron apabila cahaya menerangi mereka. Elektron yang dipancarkan dengan cara ini boleh dipanggil fotoelektrik. Menurut teori elektromagnetik klasik, kesan ini boleh dikaitkan dengan pemindahan tenaga dari cahaya ke elektron dalam logam. Dari perspektif ini, perubahan dalam kedua-dua amplitudo atau panjang gelombang cahaya akan mendorong perubahan dalam kadar pelepasan elektron daripada logam. Tambahan pula, menurut teori ini, cahaya yang cukup redup akan dijangka menunjukkan waktu lag antara cahaya awal cahaya dan pelepasan elektron berikutnya. Walau bagaimanapun, keputusan percubaan tidak dikaitkan dengan salah satu daripada dua ramalan yang dibuat oleh teori ini. Sebaliknya, ternyata, elektron hanya dicampakkan oleh kesan fotoelektrik jika cahaya mencapai atau melebihi frekuensi ambang, di mana tidak ada elektron yang boleh dipancarkan dari logam tanpa menghiraukan panjang dan pendedahan cahaya cahaya.
Definisi photoemission dalam kamus Corsica
Takrif photoemission dalam kamus adalah pelepasan elektron kerana kesan radiasi elektromagnet, esp akibat kesan fotoelektrik.
