How does issue of Bonus Share Impact A Trader

#1
I tried to post this query in some other thread but no response.

I need some knowledge on Bonus Shares.
My Question is......
E.g... ABC Company has declared that it will be issuing say 2 shares as bonus for every 1 share held on XYZ date ( Record Date ).
So if i purchase 1 share at least a week in advance of the date set , will i get the 2 shares as bonus ?:confused:
Also, will the bonus shares be issued in physical form or demat form if i have bought them in the demat form ?
How will the bonus share impact my earninigs. Will my earnings automatically double with the bonus share added or is there some other catch to it ?

The reason i am asking this is that i Hold 100 shares of Rajesh Exports bought on the 15th Jan after i got news that they are going for a stock spilt of Re 1 from Rs. 2 face value and bonus of 2 shares for every 1 share held. The date is fixed as 05th Feb.

I also have got confirmation on Satra Properties bonus issue of 2 for every 1 share and the date is fixed a 25th Jan. Can i invest in it , say tomorrow, for bonus ?

Your advise on the same would be appreciated.

Regards

Shail.
