Mode Number Solution

STEP 0: Pre-Calculation Summary

Formula Used

Mode Number = (2*Length of Cavity*Refractive Index)/Photon Wavelength
m = (2*L_c*n_ri)/λ
This formula uses 4 Variables

Variables Used

Mode Number - Mode Number indicates the number of half-wavelengths that fit into the given space.
Length of Cavity - (Measured in Meter) - Length of Cavity is a physical measure representing the distance between the two reflective surfaces (mirrors) of an optical cavity.
Refractive Index - Refractive Index is a dimensionless quantity that describes how much light is slowed down or refracted when entering a medium compared to its speed in a vacuum.
Photon Wavelength - (Measured in Meter) - Photon Wavelength refers to the distance between consecutive peaks (or troughs) in the oscillating electric and magnetic fields of a photon's electromagnetic wave.

STEP 1: Convert Input(s) to Base Unit

Length of Cavity: 7.78 Meter --> 7.78 Meter No Conversion Required
Refractive Index: 1.01 --> No Conversion Required
Photon Wavelength: 3.9 Meter --> 3.9 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

m = (2*L_c*n_ri)/λ --> (2*7.78*1.01)/3.9

Evaluating ... ...
