Question

shanti began to draw a venn diagram comparing refracting and reflecting telescopes. which label could be written in the area marked x? \uses a convex mirror\ \uses a concave mirror\ \uses a concave eyepiece lens\ \uses a convex eyepiece lens\

Explanation:

Refracting telescopes use convex lenses for both the objective and eyepiece. Reflecting telescopes use a concave mirror as the objective and usually a convex eyepiece lens. A convex eyepiece lens is common to both types of telescopes. Convex mirrors are not used in these telescopes, concave mirrors are only in reflecting telescopes, and concave eyepiece lenses are not typical for these common telescope types.

Answer:

"Uses a convex eyepiece lens"
