This results in(a) a larger angle to be subtended by the object at the eye and hence viewed in greater detail.(b) the formation of a virtual erect image.(c) increase in the field of view.(d) infinite magnification at the near point.

Answer:

(a) a larger angle to be subtended by the object at the eye and hence viewed in greater detail.

(b) the formation of a virtual erect image.

 

 

 

 

 

 

 

The object to be viewed can be brought closer to the eye than the standard near the point when using a magnifying glass. As a result, the item near the eye can subtend a bigger angle and so be perceived in greater detail. There is also the construction of a virtual erect and expanded image.
