Microscopes And Telescopes
In an astronomical telescope of refracting type :
-
Eyepiece has greater focal length.
-
Objective has greater focal length.
-
Objective and eyepiece have equal focal length.
-
Eyepiece has greater aperature than the objective
B.
Objective has greater focal length.
Draw a labelled diagram of an image formed by a compound microscope, with the image at least distance of distinct vision. Write any one expression for its magnifying power.
Image formed by a compound microscope:
(i) Define Resolving Power of a simple astronomical telescope.
(ii) State one advantage of a reflecting telescope over refracting telescope.
(i) Resolving power of a telescope is its ability to see two very closely objects just separate,
(ii) Advantage of reflecting telescope over refracting telescope is, there is no loss of light in case of reflection, image produced by a reflecting telescope is much brighter than that produced by a refracting telescope.
