Radiant flux or radiant power is the radiant energy emitted, reflected, transmitted or received, per unit time, and spectral flux or spectral power is the radiant flux per unit frequency or wavelength, depending on whether the spectrum is taken as a function of frequency or of wavelength.
Online radiant flux calculator used to calculate radiant energy emitted, reflected, transmitted or received, per unit time using radiant energy emitted, time values.
Formula:
ÎĶe = âQe ÷ ât
where,â is the partial derivative symbol
Qe is the radiant energy emitted, reflected, transmitted or received;
t is the time
ÎĶe is the Radiant flux
