Focal length for concave lens
WebTypical values of refractive indices for glass, material which a lens is made of, and that of water are 1.5, 1.33 respectively. ACCORDING TO THE lens Maker's formula the focal length of a lens is formulated as: 1/f= (u_lens/u_medium-1)* [1/R_1–1/R_2]. Web8. Suppose a cell phone screen is held 8.50 cm from a concave eyeglass lens of focal length −9.50 cm, which corrects for pronounced nearsightedness of the viewer. What magnification is produced? [di=f0/(d0−f)⋅m=−di/d0.] Reference: Example 25.8. Question: 8. Suppose a cell phone screen is held 8.50 cm from a concave eyeglass lens of ...

http://hyperphysics.phy-astr.gsu.edu/hbase/geoopt/raydiag.html WebRay Diagrams for Concave Lenses. The ray diagrams for concave lenses inside and outside the focal point give similar results: an erect virtual image smaller than the object. The image is always formed inside the focal length of the lens.
