To explain:The reason for using prisms in binoculars.
Answer to Problem 72A
The prisms in binoculars are useful for the three-dimensional view.
Explanation of Solution
Introduction:
Binoculars are used to see magnified image of the distinct object. Traditional binoculars are too long in comparison with prism binoculars.
Prism in binoculars provides the separation between eyes that gives us a sense of three-dimension and depth.
Similarly, the prisms in binoculars increase the distance between the objective lenses to obtain a clear three dimensional view of a distant object.Hence, the prisms in binoculars are useful for the three-dimensional view.
