Concave Mirror Manufacturer,Supplier and Exporter in India
Product Code : EL-PL-12435
Jlab Export is a leading Concave Mirror Manufacturer,and suppliers in India
Concave Mirror (code EL-PL-12435) is a 50 mm round converging mirror of spherical, optically worked glass, highly polished with ground edges, in a choice of 15 cm or 25 cm focal length. Students use it to form real images on the optical bench and to measure focal length. Ambala, India, is where JLab makes both focal lengths.

Where the Image Forms
With the object beyond the centre of curvature C, the image is real, inverted and smaller, between C and the focus F. At C the image is the same size and also at C; between C and F it is magnified and forms beyond C. Inside F the image becomes virtual, erect and magnified behind the mirror, the case used in shaving and make-up mirrors.
Three Ways to Find f
For a rough value, focus a distant window on a wall: the mirror-to-wall distance is close to f. For a check at C, move an object needle until it coincides with its own inverted image without parallax; that distance is R, 30 cm or 50 cm for these mirrors, and f = R/2. For an exact result, take u–v readings on the optical bench and use 1/f = 1/u + 1/v, with distances counted positive for real objects and images.
