Question

A source emits 45 joules of energy in 15 s. What is the radiant flux of the source?

Answer 1

out will come after applying the formula ofso

Answer 2

A source emits 45 joules of energy in 15 s. The radiant flux of the source is 3 W.

Explanation:

Step 1:

Given data in the question  

Net emitted  energy (E) = 45 J

Total Time (t) = 15 s  

Radiant flux :- The radiant flux is the energy that is released, that is reflected, transmitted or received per unit time and the spectral flux or spectral power shall be the flux of radiants per unit wavelength or frequency .

Step 2:

The source of radiant flux is given by,

$\text {Radiant Flux}=\frac{\text {Net emitted energy}}{\text {time}}$

                    $=\frac{45}{15}$

                    = $3 W$

The source's radiant flux is given by 3 W.
