The output of a flashlight is its light
Well, if the body emits its own light then it first has to make it. So when the light is made not all of the energy put in will become light therefore the energy created will become light, heat and sound (like a light bulb) and so the amount of energy that is wasted on heat and sound will affect the amount of light produced in the long run. Hope this helps
A prism bends light rays. White light is made up of many different wave lengths of light. A prism bends each wave length a different amount, that is why different colors are produced from the output side of a prism.
It can be.

does the amount of light affect mold growth?
decreasing the voltage and increasing the ohms

The brightness of a light bulb directly has no direct relationship with magnets and wire. The bulbs brightness is determined by the wattage of the bulb. The higher the wattage of the bulb the brighter the bulbs light output.
Increasing the amount of light entering the eyes causes the pupils to contract. Think about it, if someone shone a flashlight into your eyes, wouldn't you try to shield them?
The Moon is "waxing".
The bulb has resistance which then gets smal
no. This is because light only affect the rate of photosynthesis and not the chlorophyll concentration in the leaf
Yes, but not exlusively by increasing the amount and duration of light; Plants need nutrients and water as well, to be healthy, and probably in increased amounts along with the increased amounts of light, since more light means more growing activity.
the ISO setting in your camera controls the shutter speed therefore increasing or reducing the amount of light captured by the film/photocell
Both bulbs output the same amount of energy. The difference is in how much of that energy is output as heat vs the energy output as light. In a standard incandescent light bulb about 10% of the energy is output as light while the other 90% is output as heat. This makes the bulb only 10% efficient. For a florescent bulb the output of light is about 50% and the other 50% is output in heat. This means that a fluorescent bulb outputs five times as much light for the same wattage as a standard incandescent bulb, hence you can get the equivalent of 100 watts of light output for only 20 watts of electricity.
