Hi Rakhi,

Undelete operation in the trigger will be fired, if you are restoring deleted record from the recycle bin. Example. If you deleted an account record, then it will be moved to recycle bin, if you restore the deleted account record from recycle bin, then undelete event in account object will get triggered. 
trigger AccountUndeleteTrigger on Account (after undelete) 
{
	List<Account> listAccountToUpdate = new List<Account>();
	for(Account acc : trigger.new)
    { 
			acc.Name = 'Undeleted:' + acc.Name;
			listAccountToUpdate.add(acc);
	} 
	
	if(listAccountToUpdate.size() > 0 )
	{
		update listAccountToUpdate;
	}
	
}

I would suggest you to go thorugh below two links to get more grasps on the same.

The after undelete trigger event only works with recovered records—that is, records that were deleted and then recovered from the Recycle Bin through the undelete DML statement. These are also called undeleted records. 
//Trigger class
trigger AccountUndeleteTrigger on Account (after undelete) 
{
    if(Trigger.isAfter && Trigger.isUndelete) {
        undeleteRecord.isUndelete(trigger.new);
    }
}

//Helper Class

public class undeleteRecord {
    public static void isUndelete(List<Account> accList){ 
        system.debug('acclist--> '+acclist);
        List<Account> accListToUpdate = new List<Account>();
        Set<Id> accidset = new Set<Id>();
        for(Account acc: accList){
            accidset.add(acc.Id);
        }
        system.debug('accidset--> '+accidset);
        List<Account> accNewList = [Select Id, Name From Account Where Id=:accidset];
        for(Account ac: accNewList){
            ac.Name = 'Undeleted'+ ac.Name;
            accListToUpdate.add(ac);
        }
        update accListToUpdate;
    }
}

Please let me know if you have any query.
