What is a Empty Set??

Dear Student 
Below is the answer of your question

Empty Set :  “A set which contains no elements is called as empty set or null set”, and it is sometimes known as void set . It is usually denoted by ∅ or {}
We can say also There are some sets that do not contain any element at all. For example, the set of months with 32 days. We call a set with no elements the null or empty set. It is represented by the symbol { } or Ø .

Some other example of null sets are:
The set of dogs with six legs.   ( not possible that means empty set )
The set of squares with 5 sides. ( empty set )
Hope it helps
