Question

Thin lenses. Object O stands on the central axis of a thin symmetric lens. For this situation, each problem in the table (below) gives object distance p (centimeters), the type of lens (C stands for convegig 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 he image c real or vir al d me ted from objector noninverted, and (e) on the same side of the lens as object O or on the opposite side (a) Lens m RV I/NI Side +9.6 D, 24

Explanation / Answer

f = - 24 cm

p = 9.6 cm

(A) Applying 1/f = 1/p + 1/q

q = - 6.9cm

(B) m =-q / p = 0.71

(C) Virtual ( q is -ve)

(D) Non-inverted (m is +ve )

(E) same side (q is -ve )
