Radiation Intensity at given Distance using Beer's Law Solution

STEP 0: Pre-Calculation Summary

Formula Used

Radiation Intensity at Distance x = Initial Radiation Intensity*exp(-(Monochromatic Absorption Coefficient*Distance))
I_λx = I_λo*exp(-(α_λ*x))
This formula uses 1 Functions, 4 Variables

Functions Used

exp - n an exponential function, the value of the function changes by a constant factor for every unit change in the independent variable., exp(Number)

Variables Used

Radiation Intensity at Distance x - (Measured in Watt per Steradian) - Radiation intensity at Distance x is the radiant flux emitted, reflected, transmitted or received, per unit solid angle.
Initial Radiation Intensity - (Measured in Watt per Steradian) - Initial Radiation Intensity is the radiant flux emitted, reflected, transmitted or received, per unit solid angle.
Monochromatic Absorption Coefficient - Monochromatic Absorption Coefficient is defined as the proportionality constant where thickness of the gas layer and the intensity of radiation are proportional.
Distance - (Measured in Meter) - Distance is the length across which the absorption of radiation beam is taking place.

STEP 1: Convert Input(s) to Base Unit

Initial Radiation Intensity: 920 Watt per Steradian --> 920 Watt per Steradian No Conversion Required
Monochromatic Absorption Coefficient: 0.42 --> No Conversion Required
Distance: 0.87 Meter --> 0.87 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

I_λx = I_λo*exp(-(α_λ*x)) --> 920*exp(-(0.42*0.87))

Evaluating ... ...

I_λx = 638.405505526279

STEP 3: Convert Result to Output's Unit

638.405505526279 Watt per Steradian --> No Conversion Required

FINAL ANSWER

638.405505526279 ≈ 638.4055 Watt per Steradian <-- Radiation Intensity at Distance x

What is Radiation?

Radiation is energy that comes from a source and travels through space at the speed of light. This energy has an electric field and a magnetic field associated with it, and has wave-like properties. You could also call radiation “electromagnetic waves”.

What is Emissivity?

Emissivity is defined as the ratio of the energy radiated from a material's surface to that radiated from a perfect emitter, known as a blackbody, at the same temperature and wavelength and under the same viewing conditions. It is a dimensionless number between 0 (for a perfect reflector) and 1 (for a perfect emitter).
