Telophase II begins after the separation of sister chromatids. In this phase individual chromosomes reach at pole. Nuclear membrane starts getting formed around them and cytokinesis takes place. Cytokinesis is the division of cytoplasm.
This results in the formation of four daughter cells which are haploid.
Therefore, a 10x eyepiece used with a 40X objective lens, will produce a magnification of 400X. The naked eye can now view the specimen at a magnification 400 times greater and so microscopic details are revealed. More on objective lenses here. Magnification is the ability to view an object as larger.
