Question

Thin lenses. Object O stands on the central axis of a thin symmetric lens. For this situation, each problem in Table 34 - 6 ( below ) gives object distance p ( centimeters ) , the type of lens ( C stands for converging and D for diverging ) , and then the distance ( centimeters, without proper sign ) between a focal point and the lens. Find ( a ) the image distance i and ( b ) the lateral magnification m of the object, including signs. Also, determine whether the image is ( c ) real ( enter 1 ) or virtual ( enter 0 ) , ( d ) inverted ( enter 1 ) from object O or non inverted ( enter 0 ) , and ( e ) on the same side of the lens as object O ( enter 1 ) or on the opposite side ( enter 0 ) . TABLE 34 - 6 Problems 50 through 57: Thin Lenses. See the setup for these problems.

Explanation / Answer

For problem 52 we have p = 24 cm and f = 6.3 cm a) the image distance is found from 1/f = 1/p + 1/i 1/(6.3 cm) = 1/(24 cm) + 1/i i = 8.54 cm b) the lateral magnification is given by m=-i/p = - 8.53 cm / 24 cm = - 0.356 cm c) the image is real since the image distance is positive d) the image is inverted e) the image is on the opposite side of the lens compared to the object
