Question

наибольшая длина волны света,при котором наблюдается фотоэффект для калия

Answer 1

hν=A

(hc)/λ=A

λ=(hc)/A

Где А - работы выхода электронов для калия. с- скорость света в вакууме. h-постоянная планка.

Answer 2

Answer:

The longest wavelength of light at which the photoelectric effect is observed for potassium is approximately 310 nm.

This information is supported by the following sources: - Source "2. 4. , , 6,2 . ." - Source "... (2.1.10). max , max max . max max ..."

These sources indicate that the maximum wavelength for the photoelectric effect for potassium is around 310 nm.
