Alright, from what I remember from physics, light is the emission of a photon.
Now, the photon follow a wavelenght. If another photon, in reverse wavelenght were to enter the path of the previous photon (facing each other), then those 2 photons, light emitting particles, would actually create, no light. 2 opposing wavelength cancel out each other.
Same happens with drops of water in a pond...
For the flashlight...not sure how to use that in making it non-luminous. your flashlight is luminous because the filament inside the bulb is being heated up by the exlectric current of the batteries. The molecules inside the bulb start to move more and more thus resulting in light emission.

Do your own homework lol. Your best bet wuld be to open your textbook and do one of 2 things:
1) Read it!
2) Usually on the back or the bottom of the chapter referring to the project part you are having trouble with there will be a website you can go to for help with the section. Theres all you should need...

Try doing a web search. You can also look in the back of your book and see if there are any web sites listed that will give you more information.

If it's off it would be non-luminous.
