Luminous Intensity in Direction Normal to Surface Solution

STEP 0: Pre-Calculation Summary
Formula Used
Luminous Intensity Normal to Surface = Surface Area*Luminance Normal to Surface
In = A*Ln
This formula uses 3 Variables
Variables Used
Luminous Intensity Normal to Surface - (Measured in Candela) - Luminous Intensity Normal to Surface measures the brightness of light emitted or reflected from a surface in a specific direction, typically perpendicular to the surface.
Surface Area - (Measured in Square Meter) - Surface Area refers to the total area of a surface that light rays strike. This area determines the amount of light energy absorbed, reflected, or transmitted by the surface.
Luminance Normal to Surface - (Measured in Lux) - Luminance Normal to Surface is defined as a measure of wavelength-weighted power emitted by the light source in a particular direction per unit solid angle.
STEP 1: Convert Input(s) to Base Unit
Surface Area: 28.5 Square Meter --> 28.5 Square Meter No Conversion Required
Luminance Normal to Surface: 0.37 Lux --> 0.37 Lux No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
In = A*Ln --> 28.5*0.37
Evaluating ... ...
In = 10.545
STEP 3: Convert Result to Output's Unit
10.545 Candela --> No Conversion Required
FINAL ANSWER
10.545 Candela <-- Luminous Intensity Normal to Surface
(Calculation completed in 00.004 seconds)
