Explanation:

The 4X objective has a lower magnification. A lower - magnification objective provides a larger field of view, which makes it easier to locate the specimen and get it into focus initially. Once the specimen is located and roughly focused at low magnification, higher magnifications (10X and 40X) can be used for more detailed examination.
