WebJul 22, 2024 · 1. In a photoelectric tube the number of electrons leaving the surface of the emitter plate depends on the brightness of the incoming light (the photon density). Many of these are not directed toward the collector and end on the inner surface of the vacuum tube. Increasing a voltage which accelerates them toward the collector increases the ... WebPhotocurrent linearity is determined by measuring the small change in photocurrent as a result of a small change in the incident light power as a function of total photocurrent or incident light power. Non-Linearity is the variation of the ratio of the change in photocurrent to the same change in light power, i.e. ∆I/∆P.
