The pupil dialates to allow light to enter the eye and for you to be able to see. If there is no light at all then your eyes can not be used because you need light to see. If there is a little bit of light, close your eyes for 15 seconds so they can adjust to darkness.
Yes, you can see yourself in a mirror in a completely dark room if your eyes have adjusted to the light yet.
Not unless you have a definition of "completely dark" that means something other than completely dark (i.e. no light whatsoever).
It will illuminate very well in a completely dark room and give you enough light to work in.
Eyes depend on light to see. If there is no light, then we see nothing. However, most rooms actually aren't completely dark, even in the dead of night. Our eyes are very good at adapting to all sorts of light levels. If our eyes are kept in a very dark room, they will increase their sensitivity over a period of about twenty minutes. Then they will be able to see in with even a tiny amount of light.
No light comes around the edges.
Yes u can see the red apple b/c red is the first form of visible light
If there is no light you can not see. There is only blackness. This is quite disconcerting. If you put your hand in front of your eyes you can not see it. If the room is dark ie no light then you can not see.
The red measles causes red and sensitive eyes so a darkened room is more comfortable.
The "light fixture" was designed to be an extra step in the secret room solution. The problem was that it was so close to your feet that it is easily overlooked. You cannot interact with any room items in the dark.
its underground in a dark room....u need a glow stick to be able 2 see
No, not unless it has batteries as well as solar panels. Most calculators have solar power and batteries now. But you wouldn't be able to see the screen if you were in a dark room anyway.
It depends on however big the room is
