Terms you must know:
microscope, refracting and reflecting telescope, Antonie van Leeuwenhoek, Galileo, optical device, ray diagram, intensity, transparent, translucent, opaque, luminous, non-luminous, reflection, regular and diffuse reflection, law of reflection, normal line, incident ray, reflected ray, angle of incidence, angle of reflection, concave and convex mirror, focal point, refraction, density, lens, concave and convex lens, pupil, iris, retina, cones, rods, optic nerve, aperture, diaphragm, film, nearsightedness, farsightedness,
Be able to:
