  • A Galilean telescope has an objective of focal length 100 cm and magnifying power 50. The distance between the two lenses in normal adjustment will be

    Options
    (a) 96 cm
    (b) 98 cm
    (c) 102 cm
    (d) 104 cm

    Ans:
    fo= 100 cm
    M=50
    fo/fe = 50
    fe=100/fo
    fe=2
    L=fo-fe
    L=100-2
    L=98cm
