1} SO, here 1st is a window glass which is an example of transparent object.As from a window glass we can see the sigth of other side.

2}Translucent objects allow light,to pass through them partially,but objects on the other side can't be seen clearly.So,from butter paper we can see the sight of other sight ,but not clearly.
