Question

Both the eyepiece and the contribute to the magnification of a microscope

Answer 1

diathermie wall whi it rapidly. If two bodi separated by such a wa e equal in a short tin to bodi B 5 increases, in gener is expansion proper Now, we have independent of a n study the therm on of temperatur T and suppose i the temperature hanged to L + A expansion in th consists of hence small bjective emperature Ti C and Loa is small and rval, D=25cm Compound microscope consists of objective lens and eyepiece.. lens. The objectie lens has a very small focal length and hence aperture. The object is placed outside the focal Length of objecture but very near to it. An image is Formed due to two rays one passing from the optical centre and another paraled ray passing from the focus of the objective lens. This image is inverted, as sh above Another eyepiece lens is placed infront of this objective lens whose focal length is also small. The Image formed due to objectie lens lies inside the focal length of eyepiece lens. Hence as shown above two rays one passing from the optical centre and another from the focus of the delined in eyepiece enter the eyes. These two beams appear to come from istance vision DDV ~ 25cm denerally distance of distinct M = AB". - A"B" x A B multiply of divide by AB.
