Illuminance when Effective Intensity is Given Solution

STEP 0: Pre-Calculation Summary

Formula Used

illumination_1 = (Instantaneous Intensity*Threshold Illuminance)/Effective Intensity
E = (I*E₀)/I_e
This formula uses 3 Variables

Variables Used

Instantaneous Intensity - Instantaneous Intensity of Light (Measured in Lux)
Threshold Illuminance - Threshold Illuminance for a steady burning Light. (Measured in Lux)
Effective Intensity - Effective Intensity of Light (Measured in Lux)

STEP 1: Convert Input(s) to Base Unit

Instantaneous Intensity: 50 Lux --> 50 Lux No Conversion Required
Threshold Illuminance: 100 Lux --> 100 Lux No Conversion Required
Effective Intensity: 50 Lux --> 50 Lux No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

E = (I*E₀)/I_e --> (50*100)/50

Evaluating ... ...

E = 100

STEP 3: Convert Result to Output's Unit

100 Lux --> No Conversion Required

FINAL ANSWER

100 Lux <-- Illumination
