to anwer Question 4 points
Data provided below
The magnitude of the lateral magnification is defined to be imi = Image Height = 4 Object Height h, 3) From geometry this can be shown to be equal to From ur measurements obtained for source-screen distance equal to 85 cm, compare the yo lateral magnification using each of the two relations above. Do this for the first position o the lens (the unprimed measurements) and then for the second position of...

After taking an astronomy class, you purchase an astronomical telescope that has a focal length for the objective and eyepiece respectively of 196 cm and 1.27 cm. After using the telescope several times, you decide to increase its angular magnification by replacing the eyepiece. After replacing the eyepiece, the length of the barrel must be adjusted in order to bring objects into focus. Determine the best angular magnification you can obtain, if the barrel can only be shortened by 0.54...
