Transmittance Solution

Follow our step by step solution on how to calculate Transmittance?

FIRST Step Consider the formula

t = {(\sin (\frac{π}{λ o} \cdot {(n ri)}^{3} \cdot r \cdot V cc))}^{2}

Next Step Substitute values of Variables

∴

t = {(\sin (\frac{π}{3.939m} \cdot {(1.01)}^{3} \cdot 23m \cdot 1.6V))}^{2}

Next Step Substitute values of Constants

∴

t = {(\sin (\frac{3.1416}{3.939m} \cdot {(1.01)}^{3} \cdot 23m \cdot 1.6V))}^{2}

Next Step Prepare to Evaluate

∴

t = {(\sin (\frac{3.1416}{3.939} \cdot {(1.01)}^{3} \cdot 23 \cdot 1.6))}^{2}

Next Step Evaluate

∴

t = 0.852309483764742

LAST Step Rounding Answer

∴

t = 0.8523

How to Evaluate Transmittance?

Transmittance evaluator uses Transmittance = (sin(pi/Wavelength of Light*(Refractive Index)^3*Length of Fiber*Supply Voltage))^2 to evaluate the Transmittance, The Transmittance formula is defined as a measure of the ability of a material to allow light to pass through it. Transmittance is a measure of the ability of a material to allow the passage of light or other electromagnetic waves through it. It is the ratio of the transmitted intensity to the incident intensity of a beam of light passing through a substance. Transmittance is denoted by t symbol.

How to evaluate Transmittance using this online evaluator? To use this online evaluator for Transmittance, enter Wavelength of Light (λ_o), Refractive Index (n_ri), Length of Fiber (r) & Supply Voltage (V_cc) and hit the calculate button.

FAQs on Transmittance

What is the formula to find Transmittance?

The formula of Transmittance is expressed as Transmittance = (sin(pi/Wavelength of Light*(Refractive Index)^3*Length of Fiber*Supply Voltage))^2. Here is an example- 0.852309 = (sin(pi/3.939*(1.01)^3*23*1.6))^2.

How to calculate Transmittance?

With Wavelength of Light (λ_o), Refractive Index (n_ri), Length of Fiber (r) & Supply Voltage (V_cc) we can find Transmittance using the formula - Transmittance = (sin(pi/Wavelength of Light*(Refractive Index)^3*Length of Fiber*Supply Voltage))^2. This formula also uses Archimedes' constant and Sine (sin) function(s).
