Answer
The type of mirror shown is a flat (or plane) mirror. This type of mirror reflects light and produces an image that is the same size as the object.

Answer
The phenomenon demonstrated is reflection of light. This occurs when light rays bounce off the surface of the mirror.
Step 3

Answer
The law of reflection states that the angle of incidence is equal to the angle of reflection. This implies that the incident ray, the reflected ray, and the normal all lie in the same plane.

Answer
The image is virtual, which means it cannot be projected onto a screen.
The image is upright relative to the object.
The image is the same size as the object and located at an equal distance behind the mirror.

Answer
The relationship between distances DE and FG is that they are equal. In a plane mirror, the distance from the object to the mirror (DE) is equal to the distance from the image to the mirror (FG).
Step 9
How will an increase in the size of object A influence distance FG? Choose from INCREASES, DECREASES or REMAINS THE SAME.

Answer
The distance FG remains the same. The size of object A does not affect the distance from the image to the mirror in a plane mirror setup.
