3. ACKNOWLEDGEMENT I would like to express my sense of gratitude to all the people without whose due support this project would have been not possible. I would like to specially thank to our physics teacher Archana mam , without whose valuable guidance this project would have been truly incomplete. Thank you mam, for always guiding us in the right direction. Your advice has always been valuable to me for the successful completion of this project. I would then like to thank our parents whose moral and financial support was an indispensable component for us during the creation of this project. I would also like to thank our principal Mr. Tek Chand who provided us with such an opportunity
