1) The relation of the magnoficationa is written as

$M=\frac{{h}_{i}}{{h}_{o}}$

$h}_{i$ is the length of the image. Notice that ${h}_{i}=-3cm$ , where the minus sign indicates that the image is inverted. $h}_{o$ is the length of the object. Thus, we have

$M=\frac{-3cm}{1cm}=-3$

2)Light ray is the answer. It is a line that is perpendicular to the light's wavefronts and keeps travelling in a straight line unit until encounters a reflecting surface, then it changes its direction.
