Functions

Intensity of Transmitted Light

Intensity of Transmitted Light varies as the square of the cosine of the angle between the two planes of transmission.

Symbol: I_t

Measurement: Luminous IntensityUnit: cd

Note: Value can be positive or negative.

Formulas to find Intensity of Transmitted Light

Intensity of Light Entering the Material

Intensity of Light Entering the Material is related to the energy of the EM wave (power per unit area). So when light passes through an interface some of it is reflected and some refracted.

Symbol: I_o

Measurement: Luminous IntensityUnit: cd

Note: Value can be positive or negative.

Formulas to find Intensity of Light Entering the Material

Absorption Coefficient

The absorption coefficient defines how far light of a particular wavelength can penetrate into a material before being absorbed. The absorption coefficient in inverse length units.

Symbol: α

Measurement: NAUnit: Unitless

Note: Value can be positive or negative.

Formulas to find Absorption Coefficient

Path Length

Path Length of average number of steps along the shortest paths for all possible pairs of network nodes.

How to Evaluate Intensity of Light Transmitted?

Intensity of Light Transmitted evaluator uses Intensity of Transmitted Light = Intensity of Light Entering the Material*exp(-Absorption Coefficient*Path Length) to evaluate the Intensity of Transmitted Light, The Intensity of Light Transmitted formula is defined as The transmitted light is polarized along the axis of the polarizer. When polarized light of intensity I0 is incident on a polarizer, the transmitted intensity is given by I = I0cos2θ, where θ is the angle between the polarization direction of the incident light and the axis of the filter. Intensity of Transmitted Light is denoted by I_t symbol.

How to evaluate Intensity of Light Transmitted using this online evaluator? To use this online evaluator for Intensity of Light Transmitted, enter Intensity of Light Entering the Material (I_o), Absorption Coefficient (α) & Path Length (x) and hit the calculate button.
