help **Educational Website Text:**### Photoelectric Effect Simulation**Adjustable Parameters:**- **Incident Light: Relative Intensity**: Adjusts the intensity of light hitting the phototube. Currently set at 50%.- **Incident Light: Frequency**: Controls the frequency of the incoming light. Current value is \(7.75 \times 10^{14} \, \text{s}^{-1}\).**Phototube Metal Options:**- Sodium (selected)- Potassium- CesiumYou can reset the simulation with the "Reset" button.**Diagram Explanation:**The diagram illustrates the photoelectric effect within a phototube consisting of:- **Photo Cathode (-)**: Emits electrons when struck by light.- **Anode (+)**: Collects the emitted electrons, creating a current.A section shows the atomic structure of the photocathode material. The emitted electrons are represented as blue dots moving towards the anode. A meter measures the current produced by the ejected electrons.**Graph Analysis:**- **Axis Labels**: - X-axis: Energy of light on cathode - Y-axis: Number of ejected electrons (current)- The graph shows a step increase in current as the frequency exceeds a certain threshold.**Interactive Task:**"Now slowly move the frequency slider to higher values until electrons start being ejected. What is the threshold frequency that causes electrons to be ejected?"The input field shows the value \(7.75 \times 10^{14} \, \text{s}^{-1}\) with an error indicator, suggesting the need to adjust the frequency for electrons to begin ejection.

Given: Relative intensity of incident light = 50% To calculate: Threshold frequency to eject…
