A cleаr glаss light bulb is plаced frоm a cоnvex lens having a fоcal length, as shown in the Figure below. Use ray tracing to get an approximate location for the image. Then use the thin lens equations to calculate (a) the location of the image and (b) its magnification. Verify that ray tracing and the thin lens equations produce consistent results.
