It depends if light can travel in it or not. If not, then it will be dark and nothing can go in. If so, then it will look like space, or its surroundings, however bright or dark they are.
It means 'operate the light-switch so as to cause the light to illuminate'.
The bulb in the light switch on a Mercedes serves as a backlight to help drivers locate the switch in the dark. It helps improve visibility and adds a touch of elegance to the overall interior design of the vehicle.
the light reaction requires energy from the sun in the form of photons. these photons excite the electrons in photosystem II and results in the electrons passing through a series of redox reactions (creating a proton gradient that through chemiosmosis turns ADP into ATP) and replaces the missing electrons of photosystem I. then when photons hit photosystem II the electrons are re-energized and go through the reaction to reach NADP+ and though NADP+ reductase are accepted by the newly formed NADPH. so in short the products of the light reaction is what is required by the dark reaction (as well as 3 CO2)
The percent transmittance grew to steadily higher numbers as the experiment progressed because the light reaction was able to occur. However, the dark cuvettes had stable levels of transmittance because light is necessary to excite electrons, which, in turn, reduces the DPIP.
there is no such thing as dark, only the absence of light.

Speed of electronsYou can indeed calculate this if you have much more information. (See the nearby link.) But the surprising thing is that the electrons travel VERY SLOWLY. In fact, if the electrons had to get to the lamp before you would see the light, we would wait several seconds in the dark each time we turned on the light.So the energy transfer in a circuit is wildly different from the electron transfer.
Light Switch
It means 'operate the light-switch so as to cause the light to illuminate'.
no they dont but v3s do.
a light switch
You say "turn on the light" because that is what you do. Turning on a light means to flip the electric switch from "off" (where there is no electricity and the light is dark) to "on" (where there is electricity and the light is glowing).
there is a light switch next to the ladder click on it and it won't be dark any more
Germs multiply much quicker in light (daytime) and lessen in number in darkness. So it is better to keep your room dark (switch the lights off) when you are not there. Talha
You go home one evening: it's dark, and you open the door, feel for the light switch, turn the light on. The switch and the light are technology, they use electricity. That's one way they are related.
Your eyes switch receptor cells from mostly cones to rods, which is why you cant see color in the dark.
