1.	(i) Which type of microscope has the arrangement of lenses shown in the adjoining figure?ii. Label the figure correctly. iii. Write the working of this microscope. iv. Where does this microscope used? v. Suggest a way to increase the efficiency of this microscope.
Answer» i. Compound microscope ii. Scientifically and technically correct figure. (Object, Objective lens, Eye piece, Image) iii. Magnification is obtained by the combined effect of two lenses. The magnification occurs in two stages. The image formed by the first lens acts as the object for the second lens. Clear image can be obtained by adjusting the distance between two lenses. iv. To study small sized objects like blood cells, animal and plant cells, bacteria. v. Any relevant remedy (For example, Selection of lens with appropriate focal length)
