Optical Activity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Optical Activity = Angle from Slit Center to Light Source/(Length*Concentration at x Distance)
α = θ/(L*C_x)
This formula uses 4 Variables

Variables Used

Optical Activity - Optical Activity, the ability of a substance to rotate the plane of polarization of a beam of light that is passed through it.
Angle from Slit Center to Light Source - (Measured in Radian) - Angle from Slit Center to Light Source/Photodetector is an angle that can be defined as the figure formed by two rays meeting at a common endpoint.
Length - (Measured in Meter) - Length is the measurement or extent of something from end to end.
Concentration at x Distance - Concentration at x Distance represents the concentration of the diffusing species at a distance of x from the surface.

STEP 1: Convert Input(s) to Base Unit

Angle from Slit Center to Light Source: 25 Degree --> 0.4363323129985 Radian (Check conversion here)
