Variables

Reflectivity

Reflectivity is the fraction of incident radiation flux reflected by the body.

Symbol: ρ

Measurement: NAUnit: Unitless

Note: Value should be between 0 to 1.

Formulas to find Reflectivity

Emissivity

Emissivity is the ability of an object to emit infrared energy. Emissivity can have a value from 0 (shiny mirror) to 1.0 (blackbody). Most organic or oxidized surfaces have emissivity close to 0.95.

Symbol: ε

Measurement: NAUnit: Unitless

Note: Value should be between 0 to 1.
