To answer this question, we need to consider what is common between refracting and reflecting telescopes, as the area marked "X" in the Venn diagram represents the intersection of the two sets, meaning the characteristics that both types of telescopes share.Step 1: Understand the characteristics of refracting telescopes.- Refracting telescopes use lenses to form an image. The primary lens used is a convex lens, which bends light to a focus point.Step 2: Understand the characteristics of reflecting telescopes.- Reflecting telescopes use mirrors to form an image. The primary mirror used is a concave mirror, which reflects light to a focus point.Step 3: Determine what is common between the two.- Both types of telescopes aim to gather light and bring it to a focus to form an image. However, the means by which they do this (lenses for refracting telescopes and mirrors for reflecting telescopes) are different.Step 4: Evaluate the given options.- "Uses a convex mirror" is incorrect because refracting telescopes do not use mirrors, they use lenses.- "Uses a concave mirror" is incorrect because this is specific to reflecting telescopes.- "Uses a concave eyepiece lens" is incorrect because the eyepiece lens in telescopes is typically convex to magnify the image formed by the primary lens or mirror.- "Uses a convex eyepiece lens" is correct because both refracting and reflecting telescopes can use a convex lens in the eyepiece to magnify the image formed by the primary optic (lens or mirror).Final Answer: The label that could be written in the area marked "X" is "Uses a convex eyepiece lens".
