A compound microscope has an objective and an eye-piece of focal length 1cm and 5cm respectively. The object is located at a distance of 1.05cm close from the objective and form an image 4.17cm close to eye-piece . Find the separation of the lenses and the magnifying power of the microscope (d=25cm)
he used to answer my questions in mathematics!!!
solve this in two steps.|dw:1368205614311:dw| apply the thin lens equation one for each lens \[{1\over f}={1\over d_i}+{1\over d_o}\]
the given info: do for the first lens di for the last lens
|dw:1368205846491:dw| assume the lenses are separated by a distance of "x" then you get two simultaneous equations and one variable
i mean, "2" variables
|dw:1368205913562:dw|
what is the formula for calculating their separation ?
use the thin lens equation for each of the lenses.
what equations do you get?
what are the equations ?? how get them??
I wrote the formulae above. you should also find them in your text.
why there are 2 formulas being used ?? and how??
only one formula // but use it on each lens.. there are two lenses
you'd find it on the first post.

i am waiting for ur reply ??
i have to go to sleep ....hello u there??
"x" = assumed distance between the lenses -> one of the things to calculate
plz i cant understand ......plz tell me the solution
