What characteristic is associated with a minus lens?

  1. Slows down

  2. Minifies

  3. Reflects

  4. Disperses

The correct answer is: Minifies

A minus lens is associated with minification. Minus lenses are concave lenses that cause light rays to diverge, resulting in the image appearing smaller or minified when viewed through the lens. This minification effect is why option B is the correct choice. Options A, C, and D are not characteristics associated with a minus lens. Option A, "Slows down," is not a typical characteristic of a minus lens. Option C, "Reflects," is not related to the effects of a minus lens. Option D, "Disperses," does not describe the primary function of a minus lens in terms of image size.
