Beat Length Solution

Follow our step by step solution on how to calculate Beat Length?

FIRST Step Consider the formula

L b = \frac{λ}{B m}

Next Step Substitute values of Variables

∴

L b = \frac{1.55μm}{1E-7}

Next Step Convert Units

∴

L b = \frac{1.6E-6m}{1E-7}

Next Step Prepare to Evaluate

∴

L b = \frac{1.6E-6}{1E-7}

LAST Step Evaluate

∴

L b = 15.5m
