1. When we talk about flat mirrors, it says that the size of image appears in the mirror is the same as of the object. Is the long rectangular mirror at home that is hang on the bedroom door to see how you look like when you dress up a flat mirror? If so, then when we approach the mirror, our image is bigger but we probably can not see our whole body; when we step away from the mirror, we look smaller and can see our whole body. So does the size of the image change? Then does it sort of relate to concave mirror which is used for a magnifies image. I am confused with these concepts. 2. Can real image and virtual image both be seen in the mirror by our sight? thanks for help.
