Relative Attenuation Solution

STEP 0: Pre-Calculation Summary

Formula Used

Relative Attenuation = 10*log10(Total Power/Spectral Power)
α_m = 10*log10(P_s/P_m)
This formula uses 1 Functions, 3 Variables

Functions Used

log10 - The common logarithm, also known as the base-10 logarithm or the decimal logarithm, is a mathematical function that is the inverse of the exponential function., log10(Number)

Variables Used

Relative Attenuation - (Measured in Decibel per Meter) - Relative Attenuation is defined as the reduction in the intensity or power of light as it passes through a material or medium, often in comparison to a reference material or medium.
Total Power - (Measured in Watt) - Total Power is the measurement of all the power transmitted through the fiber.
Spectral Power - (Measured in Watt) - Spectral Power refers to the distribution of power or intensity of electromagnetic radiation as a function of its wavelength or frequency.

STEP 1: Convert Input(s) to Base Unit

Total Power: 5.5 Watt --> 5.5 Watt No Conversion Required
Spectral Power: 2.5 Watt --> 2.5 Watt No Conversion Required

STEP 2: Evaluate Formula

What is the significance of Relative Attenuation?

Relative attenuation in optics is crucial because it measures the reduction in the intensity of light or any electromagnetic wave as it passes through a medium. This parameter helps us understand how much the light is absorbed or scattered, which is essential for various applications, such as telecommunications, medical imaging, and material characterization.

How to Calculate Relative Attenuation?

Relative Attenuation calculator uses Relative Attenuation = 10*log10(Total Power/Spectral Power) to calculate the Relative Attenuation, Relative Attenuation in optics refers to the reduction in the intensity or power of light as it passes through a material or medium, often in comparison to a reference material or medium. It is a measure of how much the light is absorbed, scattered, or otherwise diminished as it travels through the substance. Relative Attenuation is denoted by α_m symbol.

How to calculate Relative Attenuation using this online calculator? To use this online calculator for Relative Attenuation, enter Total Power (P_s) & Spectral Power (P_m) and hit the calculate button.
