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 but also use a convex eyepiece lens. The area marked \( X \) is the common part (both). Convex eyepiece lens is used in both types. Convex mirror is not used in either. Concave mirror is only in reflecting. Concave eyepiece lens is not used in standard refracting or reflecting setups.

Answer:

“Uses a convex eyepiece lens”
