Absorbed Power Solution

Follow our step by step solution on how to calculate Absorbed Power?

FIRST Step Consider the formula

P abs = P i \cdot \exp (- b \cdot α)

Next Step Substitute values of Variables

∴

P abs = 0.22W \cdot \exp (- 0.46μm \cdot 15608.42cm⁻¹)

Next Step Convert Units

∴

P abs = 0.22W \cdot \exp (- 4.6E-7m \cdot 1.6E+6m⁻¹)

Next Step Prepare to Evaluate

∴

P abs = 0.22 \cdot \exp (- 4.6E-7 \cdot 1.6E+6)

Next Step Evaluate

∴

P abs = 0.107301242188786W

LAST Step Rounding Answer

∴

P abs = 0.1073W
