Open the blinds during the day!
In a dark room, a mirror will not reflect anything because there is no light for it to bounce off of and create a reflection. Mirrors require light to reflect images.
Anything that you can't see in a dark room. Like my shoes, for example.
Your pupil's have to adjust from the light to the dark so your pupils will get bigger in a dark room.
The heat capacity of a room is the same, whether it's lighted or dark, although a lit room will be warmer than a dark room (all other factors being the same). Adding mass to a room will change its heat capacity. More mass will slow down a temperature change. Less mass will speed it up.
Light in a dark room gets absorbed by the surfaces in the room or scattered by particles in the air, eventually dissipating as heat. If no light sources are present, the room remains dark as there is no light to reflect off objects and be detected by our eyes.
No, electromagnetic rays are not present in a dark room. Electromagnetic rays are forms of light, so in a dark room there is no visible light present.
Light colors reflect and dark colors absorb.
No, shadows are created by blocking light. In a dark room, there is no light to create shadows, so you cannot catch a shadow.
Turn on the light and walk out the door.
In a completely dark room, there is no light to create shadows. Shadows are formed when an object blocks light from a source, so in the absence of light, there are no shadows visible.
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.
Black will be the color of a yellow object in a dark room while white light falls on it.
