Sci10 q2 Third Summative Test 1

This document contains a science test with 10 multiple choice questions about optics and the properties of mirrors and lenses. The test asks about the type of image formed by plane mirrors and lenses in different situations, such as whether the image is real or virtual, upright or inverted, and its size relative to the object. It also asks about specific optical devices like microscopes, cameras, and telescopes and their imaging properties.
