What will likely happen if a lens has a short focal length?

• A. The image will be smaller
• B. The image will be blurred
• C. The image will be magnified more
• D. The image will be inverted

Answer: (C)

When a lens has a short focal length, it is typically able to produce a larger magnification compared to a lens with a longer focal length. This is because the focal length is inversely related to the ability to magnify. A lens with a short focal length converges light rays more quickly, allowing it to capture more details of the object being viewed and project them as a larger image on the opposite side of the lens. Additionally, when considering the nature of lenses, shorter focal lengths often mean that the lens can create images that are larger in comparison to the original object, especially when the object is located at a distance greater than the focal length. This characteristic is particularly advantageous in applications like microscopes, where high magnification is desired to observe small details. While it is true that a lens can also produce inverted images and blurred images, these factors are not inherently tied to the focal length. Inversion of the image is a quality of lenses in general, depending on the arrangement and type of lens. Blurriness usually results from improper focus or the lens being used outside its optimal range, rather than directly from the focal length itself. Thus, the statement regarding magnification aligns most closely with the effects of having a short focal length in optics
