Answer:
The best angular magnification is
-375
Explanation:
Fe = Fo - L
From the question, (Fo) = 1.08 cm while (L) = 0.56cm
Thus, Fe = 1.08 - 0.56 = 0.52cm
Now, let's apply the angular magnification equation ;
M = - Di/Do
Where Di is the distance from the lens to the image and Do is the distance of the object to the lens.
In this question, Di is represented by f which is the distance from the lens to the image and it is f= 195cm
Also,Do is represented by Fe which is 0.52cm and it is the distance of the object to the lens.
Thus m = - f/fe = - 195/0.52 = - 375
