Photoelectron rate and saturation photocurrent (I_sat ∝ I_light (for ν > ν₀); K_max independent)
jee-mainneet-ug
I_sat ∝ I_light (for ν > ν₀); K_max independent of I_light
What each symbol means
| Symbol | What it stands for |
|---|---|
| ν | Frequency (must exceed ν₀) |
| I_sat | Saturation photocurrent (A) |
| I_light | Incident light intensity (W/m²) |
When to use this
Each photon ejects at most one electron (one-to-one at ordinary intensities); more photons per second ⇒ more photoelectrons ⇒ higher saturation current. K_max fixed by ν.
