Question
Consider a simple setup with a single lens and a real object. In which of the following cases is it possible to obtain a real image (that is, an image that can actually be viewed on a screen)? Please note that you must select the most GENERAL case that will satisfy this condition.using a convex lens, with the object located beyond the focal point of the lens
using a convex lens, with the object located between the lens and the focal point
using a concave lens, with the object located between the lens and the focal point
using a concave lens, with the object located beyond the focal point of the lens
using either a convex or concave lens, with the object located beyond the focal point of the lens
A shaving or makeup mirror is useful because it gives a magnified image that is upright (it would be hard to do your makeup with an inverted image!). Which type of mirror accomplishes this effect, and what should its focal length be?
concave mirror, with a focal length greater than the object distance
concave mirror, with a focal length equal to the object distance
convex mirror, with a focal length smaller than the object distance
convex mirror, with a focal length greater than the object distance
concave mirror, with a focal length smaller than the object distance
Explanation / Answer
a) using a convex lens, with the object located beyond the focal point of the lens b) concave mirror, with a focal length greater than the object distance
