Ishning bajarilish tartibi

1.Ikkinchi vazifada to’yinish fototokining yorug’lik intensivligiga bog’lanishi o’rganiladi. Buning uchun T₁ tirqish maksimal ochiladi va barabanli vintni burab, fototok maksimal qiymatiga mos keluvchi holati topiladi. So’ng T₁ tirqish oralig’i ma’lum qadam bilan kamaytirilib, unga mos keluchi fototok yozib olinadi. Fotoelementga tushayotgan yorug’lik nurinig intensivligi T₁ tirqish kengligiga (d) ga to’g’ri proportsional bo’lgani uchun, T₁ tirqish kengligi bilan fototok orasidagi bog’lanishni aniqlash kifoya. O’lchashlarda tirqish oralig’ini 0,2 mm qadam bilan o’zgartirib borish ma’qul.
2.Fotoeffektning qizil chegarasiga mos keluvchi ₀ ni aniqlab, unga mos keluvchi fotoelektronlarning chiqish ishi quyidagi formula asosida hisoblanadi.
.
Tirqish 2mm
Baraban 3500⁰
Fototok bilan λ orasidagi bog’lanish.
3.Ish bajarilib bo’lingach, qurilmaga berilayotgan tok manbalarini o’chirish esdan chiqmasligi kerak.
