Optical Path Difference given Fringe Width Solution

STEP 0: Pre-Calculation Summary

Formula Used

Optical Path Difference = (Refractive Index-1)*Thickness*Fringe Width/Wavelength
Δ = (RI-1)*t*β/λ
This formula uses 5 Variables

Variables Used

Optical Path Difference - Optical Path Difference is the product of the geometric length of the path followed by light through a given system, and the refractive index of the medium through which it propagates.
Refractive Index - The refractive index of a medium is defined as how the light travels through that medium. It is a dimensionless measure.
Thickness - (Measured in Meter) - Thickness is the distance through an object.
Fringe Width - (Measured in Meter) - Fringe Width is the distance between two maxima of successive order on one side of the central maxima.
Wavelength - (Measured in Meter) - Wavelength can be defined as the distance between two successive crests or troughs of a wave.

STEP 1: Convert Input(s) to Base Unit

Refractive Index: 1.333 --> No Conversion Required
Thickness: 100 Centimeter --> 1 Meter (Check conversion here)
Fringe Width: 51.07 Centimeter --> 0.5107 Meter (Check conversion here)
Wavelength: 26.8 Centimeter --> 0.268 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Δ = (RI-1)*t*β/λ --> (1.333-1)*1*0.5107/0.268

What is Refractive Index?

The refractive index is a measure of how much a material slows down light compared to its speed in a vacuum. It is calculated as the ratio of the speed of light in a vacuum to the speed of light in the material. A higher refractive index indicates that light travels more slowly in the material.
