Refractive Index Difference Solution

STEP 0: Pre-Calculation Summary

Formula Used

Difference Refractive Index = (Fringe Displacements Number*Wavelength of Light)/Slab Thickness
δn = (q*λ)/x
This formula uses 4 Variables

Variables Used

Difference Refractive Index - Difference Refractive Index is the difference between refractive indices caused due to fringe displacements.
Fringe Displacements Number - Fringe Displacements Number also referred as fringe shift defines the number of times the fringe displacement has occurred.
Wavelength of Light - (Measured in Meter) - Wavelength of Light refers to the distance between two consecutive peaks or troughs of an electromagnetic wave in the optical spectrum.
Slab Thickness - (Measured in Meter) - Slab Thickness is the measurement of how thick the slab of fiber is.

STEP 1: Convert Input(s) to Base Unit

Fringe Displacements Number: 60000 --> No Conversion Required
Wavelength of Light: 1.55 Micrometer --> 1.55E-06 Meter (Check conversion here)
Slab Thickness: 1.6 Meter --> 1.6 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

δn = (q*λ)/x --> (60000*1.55E-06)/1.6

Evaluating ... ...

δn = 0.058125
