A certain metal was initiated with light of frequency 3.2×1016 Hz. Th – InterviewSolution

1.	A certain metal was initiated with light of frequency 3.2×1016 Hz. The photoelectrons emitted had twice the kinetic energy as the same metal was irradiated with light of frequency 2×1016Hz. Calculate the threshold frequency.
Answer» A certain metal was initiated with light of frequency 3.2×10¹⁶Hz. The photoelectrons emitted had twice the kinetic energy as the same metal was irradiated with light of frequency 2×10¹⁶Hz. Calculate the threshold frequency.
