optics,how many images will the object form?
the lens shown in figure 19.16(http://img705.imageshack.us/img705/5066/figure1916.png made of two different materials . a point object is placed on the axis...how many images will the object form?
1/f = (n-1) [1/R1 - 1/R2], where f is the focal length, n is the refractive index, R1,R2 - radii of the curvature of refracting surfaces.
i didnt reach the answer but i think it has something with refractive index , and focal lenth...please help..
