PHYSICS A compound microscope consists of an objective LENS of focal length 2.0cm and an eyepiece of focal length 6.25cm separated by a distance of 15cm. How far from the objective should an object be PLACED in order to OBTAIN the final image at: (a) the least distance of distinct vision (25cm), and (b) at infinity? What is the magnifying power of the microscope in each case? MEDIUM Help best friend Study later VIDEO EXPLANATION  ANSWER Focal length of the objective lens f1=2cm Focal length of the eyepiece,f2=6.25cm Distance between the objective lens and the eyepiece,d=15cm Least distance of distinct vision,d′=25cm Image distance for the eyepiece,v2=−25cm bject distance for the eyepiece = u2 According to the lens formula f21=v21−u21 6.251=−251−u21 u2=−5cm Image distance for the objective lens v1=d+u Explanation: HOPE IT HELPS. PLEASE MARK ME AS BRAINLIEST. THANKS... |
