Expert Answer:

Empty Relation means the relation which does not have any element.
Suppose we were to define the relation R "sister of"  on the set of  boys school then it turns out to be a empty relation.
Again in terms of numbers
Consider the set A={1,2,3} B = {2,6,8}
Now if R is the relation square of from A to B
then R  is a empty relation
