A child has near point at 10 cm. What is the maximum angular magnification the child can have
with a convex lens of focal length 10 cm?
Given data-
Focal length of the convex lens ,f = 10cm
Near point of the eyes ,D = 10cm
The maximum angular magnification of the child when the image is formed at distance D=10cm
is
Hence, the angular magnification is 2.0 when the near point is 10cm
