Reflection Coefficient Solution

Follow our step by step solution on how to calculate Reflection Coefficient?

FIRST Step Consider the formula

r = \frac{V swr - 1}{V swr + 1}

Next Step Substitute values of Variables

∴

r = \frac{1.88 - 1}{1.88 + 1}

Next Step Prepare to Evaluate

∴

r = \frac{1.88 - 1}{1.88 + 1}

Next Step Evaluate

∴

r = 0.305555555555556

LAST Step Rounding Answer

∴

r = 0.3056
