Questions... just behind the mirror

WE HAD SOME QUESTIONS.....


1. Name the type(s) of mirror that forms...
     (A)A real image?
            Concave mirrors. Only a concave mirror can create a real image, due to the light rays converging, meaning they actually recombine back together.

     (B)A virtual image?
          Convex mirrors. The image is always seen behind the mirror.

     (C)A virtual image that is larger than the object?
           Concave mirrors can make the image larger.

     (D)A virtual image that is the same size as the object?
           Convex mirrors make you look the same size.
             (Virtual image- An image located where reflected rays only seem to originate) 

2. Imagine you have sprayed a bowl with shiny, reflective paint.
     (A)Which part of the bowl serves as a convex mirror?
           The part of the bowl that doesn't hold the food.

     (B)Which part of the bowl serves as a concave mirror?
           The part of the bowl that holds the food.

     (C)How do you hold the bowl to see an inverted image of you?
           You hold the bowl

     (D)How do you hold the bowl to see a larger, upright image of you?
          You hold the bowl so the base is facing you

     (E)How should you hold the bowl to see a smaller, upright image of your face?
          You should hold the bowl so you are facing the part which the food goes into.

3.In a funhouse, which kind of mirror would you use to...
