Not unless you have a definition of "completely dark" that means something other than completely dark (i.e. no light whatsoever).
Yes, a flashlight beam will reflect off a mirror in a dark room as long as the mirror is reflective. The reflected light will illuminate the area where the mirror is facing.
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.
Mirrors rely on light to reflect images. In a dark room, there isn't enough light for the mirror to reflect your image back to you.
No, you would not be able to see a mirror in a dark room as mirrors require light to reflect an image. Without light, the mirror cannot reflect any visual information back to your eyes.
It may be possible if there is enough light in the room to see an outline of your reflection in the mirror. Or, your eyes may adjust to the dimness of the room and you may see a faint outline of your reflection in the mirror.
take a mirror on go in the bath room and turn your back to the bathroom mirror and braid
In a dark room, there is no light to reflect off your body and back into your eyes, so you can't see your reflection in the mirror. Mirrors work by reflecting light, so in the absence of light, there is nothing to see.
I see that someone had been watching youtube lately :) But, to answer your question, a mirror is the colour of what it is reflecting. For example, if you were wearing a completely purple outfit and you were in a completely purple room, the mirror would be purple.
It will illuminate very well in a completely dark room and give you enough light to work in.
An elephant in a dark room? Well, anything in a dark room. Or your back, face(Excluding nose) ... you can feel them, but without the help of a mirror, you can't see them.
