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.
An iris diaphragm controls the amount of light admitted to a lens. Closing the iris diaphragm will decrease the brightness and increase the contrast of an image.
no. This is because light only affect the rate of photosynthesis and not the chlorophyll concentration in the leaf
Three factors that affect a star's brightness are the star's distance from earth, its age and its luminosity. The farther the star is from earth, the less bright it appears. As a star increases in age, its brightness also increases. Its brightness also depends on its luminosity, which is the amount of energy the star emits per second.
A pencil has nothing to do with the brightness of a light bulb.
It depends on light. it is changing with light.
Brightness refers to amount of light, 100% is maximum light and 0% is minimum light or no light - black.
The amount of energy used by a lightbulb does not affect a plants growth, only the brightness and spectrum of the light produced.
An iris diaphragm controls the amount of light admitted to a lens. Closing the iris diaphragm will decrease the brightness and increase the contrast of an image.
the brightness hurts your eye rods
The observer.

By definiton, "dark" matter neither emits or absorbs light. Thus, it does not effect the brightness of galaxies.
You need to purchase a Fluorescent dimmer switch, no circuit can dim the brightness of the light safely.

yes it can be powered by a potato:)
if light is low it can cuase the bulb brightnees.
