Question

1. which two optical devices use convex lenses to focus and enlarge images? (1 point)

a compound microscope and a camera
a refracting telescope and a reflecting telescope
a refracting telescope and a camera
a refracting telescope and a compound microscope

Explanation:

• A compound microscope uses convex lenses (objective and eyepiece) to focus and enlarge small objects. The objective lens forms a magnified real image, and the eyepiece further magnifies this image.
• A refracting telescope also uses convex lenses. The objective lens gathers light and forms an image, and the eyepiece magnifies this image.
• A camera uses a convex lens to focus light onto the film or sensor but does not enlarge the image in the same sense as magnification for viewing small details (it records the image as is, with the option to print larger but that's a post - process, not an optical magnification in the device).
• A reflecting telescope uses a concave mirror as the primary light - gathering element, not a convex lens.

Answer:

a refracting telescope and a compound microscope
