Final answer:
When two cones are shown with the apexes together, it typically indicates a telescope or a similar optical device. This arrangement of two lenses, a convex objective and a concave eyepiece, produces an upright image and is commonly used in spyglasses and opera glasses.
Step-by-step explanation:
When two cones are shown with the apexes together, it typically indicates a telescope or a similar optical device. This arrangement of two lenses, a convex objective and a concave eyepiece, produces an upright image and is commonly used in spyglasses and opera glasses. It is the same construction method used by Galileo for his telescope.
