Absolute Intensity of Atom Line Solution

Follow our step by step solution on how to calculate Absolute Intensity of Atom Line?

FIRST Step Consider the formula

I abs = (\frac{d}{4 \cdot π}) \cdot A qp \cdot n \cdot [hP] \cdot ν qp

Next Step Substitute values of Variables

∴

I abs = (\frac{1.2E+8m}{4 \cdot π}) \cdot 671/s \cdot 7801/cm³ \cdot [hP] \cdot 340Hz

Next Step Substitute values of Constants

∴

I abs = (\frac{1.2E+8m}{4 \cdot 3.1416}) \cdot 671/s \cdot 7801/cm³ \cdot 6.6E-34 \cdot 340Hz

Next Step Convert Units

∴

I abs = (\frac{1.2E+8m}{4 \cdot 3.1416}) \cdot 671/s \cdot 7.8E+81/m³ \cdot 6.6E-34 \cdot 340Hz

Next Step Prepare to Evaluate

∴

I abs = (\frac{1.2E+8}{4 \cdot 3.1416}) \cdot 67 \cdot 7.8E+8 \cdot 6.6E-34 \cdot 340

Next Step Evaluate

∴

I abs = 1.12428321441551E-13W/sr

LAST Step Rounding Answer

∴

I abs = 1.1E-13W/sr
