An researching team are working with an optical system which is
employed to watch the movement of birds. It has two biconvex lenses
and a camera without lens to watch the birds. The system features a
lens (lens) with a focal distance of 30 cm placed 40 cm from the
birds and before the camera sits an eyepiece with a focal distance
of 20 cm. By varying the space between lens and eyepieces, you'll
change the main target of the optical system. The distance between
the lens and eyepiece are varied between: a) 2 m; b) 1.5 m; and c)
1 m you get three configurations of the optical system. for every
configuration specify: where the ultimate image ends, example the
camera's detector should be placed; and what the entire
magnification are going to be . Are the pictures straight or
inverted? Are they real or virtual?
d) Describe the function of an aperture stop in a optical system?
Mention one example.
