LDF will grow it should. it is its nature. but we need to manage the files ? whats the recovery model ? simple or full ? are you taking its regular backup ? see this link

As you state that you are a new DBA, I would strongly recommend reading the Accidental DBA guide (link in my signature below) as it will cover some of the main issues which are faced in the world of SQL.
But as Bhuvnesh, what is the recovery model of the database? If FULL or BULKLOGGED do you have transaction log backups running?

Do you do transaction log backups?
Do you need the databases to be in full recovery?
What is your acceptable amount of data loss? What is your recovery point objective? Can you loose a days worth of data with no affects to the business, or can you only loose minutes?
How often do you do full or differential backups?

You should keep it to simple recovery model, untill u dont think your all transactions should logged in log file till the database backup process and it increses size of your log file..
OR you should take backup periodically..

Well i have gone through the articles mentioned above. Currently there is no transaction back up. database is in full recovery.
Will it be useful if we run the below query when there is no transaction active?
USE DBNAME;
GO
-- Truncate the log by changing the database recovery model to SIMPLE.
ALTER DATABASE DBNAME
SET RECOVERY SIMPLE;
GO
-- Shrink the truncated log file to 1 MB.
DBCC SHRINKFILE (DBNAME_Log, 1);
GO
-- Reset the database recovery model.
ALTER DATABASE DBNAME
SET RECOVERY FULL;
GO

Do you need the database to be in FULL recovery?
As I have said what is your acceptable amount of data loss? How much data can you afford to loose with this database?
