Here is how the Irradiance equation looks like.

1.5101 = 1.51 \cdot \exp (1.502 \cdot 51)

1.5101W/m² = 1.51W/m² \cdot \exp (1.502 \cdot 51μm)

1.5101 = 1.51 \cdot \exp (1.502 \cdot 51)

Irradiance Solution

Follow our step by step solution on how to calculate Irradiance?

FIRST Step Consider the formula

I t = E o \cdot \exp (k s \cdot x l)

Next Step Substitute values of Variables

∴

I t = 1.51W/m² \cdot \exp (1.502 \cdot 51μm)

Next Step Convert Units

∴

I t = 1.51W/m² \cdot \exp (1.502 \cdot 5.1E-5m)

Next Step Prepare to Evaluate

∴

I t = 1.51 \cdot \exp (1.502 \cdot 5.1E-5)

Next Step Evaluate

∴

I t = 1.51011567345035W/m²

LAST Step Rounding Answer

∴

I t = 1.5101W/m²
