Rayleigh Scattering Solution

Follow our step by step solution on how to calculate Rayleigh Scattering?

FIRST Step Consider the formula

α R = \frac{C}{λ^{4}}

Next Step Substitute values of Variables

∴

α R = \frac{7E-25}{{1.55μm}^{4}}

Next Step Convert Units

∴

α R = \frac{7E-25}{{1.6E-6m}^{4}}

Next Step Prepare to Evaluate

∴

α R = \frac{7E-25}{{1.6E-6}^{4}}

Next Step Evaluate

∴

α R = 0.121274989956915dB/m

LAST Step Rounding Answer

∴

α R = 0.1213dB/m

How to Evaluate Rayleigh Scattering?

Rayleigh Scattering evaluator uses Rayleigh Scattering = Fiber Constant/(Wavelength of Light^4) to evaluate the Rayleigh Scattering, Rayleigh scattering is a phenomenon in optics that describes the scattering of light or other electromagnetic waves by particles or objects much smaller than the wavelength of the light. Rayleigh scattering is responsible for the blue colour of the sky during the day and the reddish hues of sunrise and sunset, among other optical effects. Rayleigh Scattering is denoted by α_R symbol.

How to evaluate Rayleigh Scattering using this online evaluator? To use this online evaluator for Rayleigh Scattering, enter Fiber Constant (C) & Wavelength of Light (λ) and hit the calculate button.

FAQs on Rayleigh Scattering

What is the formula to find Rayleigh Scattering?

The formula of Rayleigh Scattering is expressed as Rayleigh Scattering = Fiber Constant/(Wavelength of Light^4). Here is an example- 1.2E+29 = 7E-25/(1.55E-06^4).

How to calculate Rayleigh Scattering?

With Fiber Constant (C) & Wavelength of Light (λ) we can find Rayleigh Scattering using the formula - Rayleigh Scattering = Fiber Constant/(Wavelength of Light^4).

Can the Rayleigh Scattering be negative?

No, the Rayleigh Scattering, measured in Attenuation cannot be negative.

Which unit is used to measure Rayleigh Scattering?

Rayleigh Scattering is usually measured using the Decibel per Meter[dB/m] for Attenuation. Neper per Meter[dB/m], Decibel per Kilometer[dB/m] are the few other units in which Rayleigh Scattering can be measured.
