A light source generates and emits its own light. A reflector reflects light (i.e. light bounces off of it) from another source. Examples of light sources: The sun, the stars, a lightbulb, a flame, a red-hot piece of metal. Examples of reflectors: The moon, the planets, the ground lit by the sun.
Only experience can tell you that. A source whose information checks out when compared to reality (e.g. other sources) is usually reliable, while a source whose data turns out not to match reality would be considered unreliable.
The terminology E.M.F is the voltage output of a power source e.g a transformer bank, generator. As relates to potential difference it's a linear electrical field strenght between 2 points. E.g the charged plates of a capacitor.
It depends on the luminescence of the materials. I see no difference between "the light source" and "the intensity of the light". Please restate and/or clarify the question.
A secondary source analyses and interprets a primary source. Some examples would be: a text book; the results for an experiment; or a website.

the difference between the source freq. and the reference freq
The path difference is the difference in the physical distance between the two sources to the observer, i.e., the difference in distance travelled from the source to the observer.
The purpose of the source tries to explain why a given source was used while the context explains the setting.
The answer is in the question itself. Open-source software has it's source code available to everyone. Closed-source software does not.
