Answer:
6.83 cm
Explanation:
Given data:
Focal length of the eye piece, = 2.50 cm
Focal length of the converging lens, f = 1.00 cm
distance of the object, p = 1.30 cm
Now,
we have the lens equation as:
q is the distance of the image
thus,
on substituting the values in the above equation, we get
or
q = 4.33 cm
now, the image is formed at the focal point of the eye piece,
therefore, the distance between the objective and the eyepiece, d = + q = 2.50 cm + 4.33 cm
or
d = 6.83 cm
