Average Radiation Intensity Solution

Follow our step by step solution on how to calculate Average Radiation Intensity?

FIRST Step Consider the formula

R avg = \frac{U}{D a}

Next Step Substitute values of Variables

∴

R avg = \frac{27W/sr}{0.08}

Next Step Prepare to Evaluate

∴

R avg = \frac{27}{0.08}

LAST Step Evaluate

∴

R avg = 337.5W/sr
