Intensity of Light in Photo Electric Effect Solution

STEP 0: Pre-Calculation Summary

Formula Used

Intensity of light = Number of Photons/(Area*Time for Photoelectric Effect)
I = n_p/(A*T_{photoelectric})
This formula uses 4 Variables

Variables Used

Intensity of light - (Measured in Candela) - Intensity of light is a measure of the wavelength-weighted power emitted by a light source in a particular direction per unit solid angle.
Number of Photons - The Number of Photons is the total massless photons that move with the speed of light in vacuum.
Area - (Measured in Square Meter) - The area is the amount of two-dimensional space taken up by an object.
Time for Photoelectric Effect - (Measured in Second) - Time for Photoelectric Effect is the continued sequence of existence and events that occurs in an apparently irreversible succession from the past, through the present, into the future.

STEP 1: Convert Input(s) to Base Unit

Number of Photons: 90 --> No Conversion Required
Area: 50 Square Meter --> 50 Square Meter No Conversion Required
Time for Photoelectric Effect: 5 Year --> 157784760 Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

I = n_p/(A*T_{photoelectric}) --> 90/(50*157784760)

Evaluating ... ...

I = 1.14079458624521E-08

STEP 3: Convert Result to Output's Unit

1.14079458624521E-08 Candela --> No Conversion Required

FINAL ANSWER

1.14079458624521E-08 ≈ 1.1E-8 Candela <-- Intensity of light

What is Intensity of light in photo-electric effect?

In the photoelectric effect, light incident on the surface of metal causes electrons to be ejected. The number of emitted electrons and their kinetic energy can be measured as a function of the intensity and frequency of the light. The number of photoelectrons emitted is proportional to the intensity of incident light.
