normalization

i have a database class.my teacher using mysql.i have a problem in normalization.anyone can tell me how to different normalization 1,2,3?i really want to know it.my teacher will ask me at the next meeting

ehm i hope im right.if im not mistaken the first is to divide the table into two or more specific table,it to make the redundancy become less.and if they was making the first,they can divide again into more specific tables to avoid redundancy it called the second(norm 2).And the last is same like others,but it must have fullfil the second state first.
