Coherence Length of Wave Solution

Follow our step by step solution on how to calculate Coherence Length of Wave?

FIRST Step Consider the formula

l C = \frac{{(λ wave)}^{2}}{2 \cdot Δλ}

Next Step Substitute values of Variables

∴

l C = \frac{{(9.9m)}^{2}}{2 \cdot 12m}

Next Step Prepare to Evaluate

∴

l C = \frac{{(9.9)}^{2}}{2 \cdot 12}

Next Step Evaluate

∴

l C = 4.08375m

LAST Step Rounding Answer

∴

l C = 4.0838m
