**Plano-Convex Lens Equation and Explanation**

The stronger the lens, the shorter is the focal length. Convex lenses have a positive power, and concave lenses a negative power. (The word, 'focus', comes from the Greek word meaning 'hearth'.... A plano-convex lens is a convergent lens with one flat surface and one convex surface. It focuses parallel light rays to a positive focal point to form real images that can be manipulated using

Materials • ray box • power supply • sheet of paper • plastic convex lenses • glass convex lens or a magnifying glass Method Before you start this activity, create a POE chart for the types of images you... Graphs for convex and concave lenses (Real is positive sign convention) Figure 1 shows a graph where the reciprocal of the image distance is plotted against the reciprocal of the object distance. The graph is a straight line that intercepts both axes at 1/f where f is the focal length of the lens. Since the object is real this graph is for a convex lens. Figure 2 shows a graph of the object

## How To Find Focal Length Of Convex Lens

### The distance from this point to the lens is also known as the focal length, though it is negative with respect to the focal length of a converging lens. Convex-concave (meniscus) lenses can be either positive or negative, depending on the relative curvatures of the two surfaces.

- The stronger the lens, the shorter is the focal length. Convex lenses have a positive power, and concave lenses a negative power. (The word, 'focus', comes from the Greek word meaning 'hearth'.
- Depending on the focal length of the specific lens, this distance might be anywhere from a few meters to a kilometer. If the object is very far, say 93,000,000 miles (1.5 x 10 11 m) like the Sun, the distance is sufficiently far that light rays are essentially parallel.
- 1/04/2013 · I'm studyng about focal lengths in convex and concave lenses, and I'm confused about how the focal lense changes. The question says "Using a diagram, explain whether the focal length would be greater in (a) a thick or thin convex lens (b) a thick or thin concave lens."
