Look! It's the Sun! And another one... and another one?

Natural Category Demonstrating Reflection:

This is a picture I took on my way to school one morning of the sunrise. I looked out my window and noticed I could see the sun in both the mirror, and the side of the car. The law of reflection states that on a straight planed mirror, the angle of incidence is equal to the angle of reflection in respect to the normal. Basically this means the angle at which the, in this case, light of the sun hits the mirror, you view the image of the sun at the same angle that it hits the mirror. The normal is an imaginary line that is perpendicular to the surface of the mirror. This mirror however, is convex or diverging. This means the mirror is curved outwards and the image seems to be smaller than it actually is. That is why all car mirrors have the warning “objects in mirror are closer than the appear” which can be seen at the bottom of the mirror. Now, the reason there are three suns in this picture is very simple. The sun’s image is viewed in three spots, an image in the sky, in the window, and in the door, the image in the window and in the door are both reflected twice. Once, in the window and door, then that image is reflected again into the mirror, causing the illusion of the three suns.
