B.Sc Physics

Since universities offering undergraduate programme in Astronomy are rarely found, one can join for a major/ honours in Physics with Mathematics as a subsidiary subject. Thereafter, take a master's degree in Physics or Astronomy. After the successful completion of M.Sc. One can do specialisation in astronomy leading to Ph.D. which enables one to become an astronomer/ astronaut/ astrophysicist or a scientist/ research officer etc. In the field of space research. Please check for your eligibility to pursue B.Sc. Physics from the criteria mentioned below:

Hello dear,
Since graduation is a foundation course. You won't specialise in any particular field during your graduation. Your syllabus is set in order to touch upon all the topics of physics in order to make it easy for students to identify their interests and to pursue masters as per the individual's interest.
The main topics are:
Mathematical physics:
a) Differential equations and vectors.
b) Fourier Analysis and Special Functions.
c) Complex Analysis.
Mechanics (Newtonian)
Electrodynamics
Waves and optics
Digital and Analogue systems
Thermodynamics
Quantum Mechanics
Statistical Physics.
Atomic and Nuclear Physics.
In addition to these, keeping in mind the recent fields of latest researches, there are DSE papers, as per your interests which includes :
Nanoscience
Atmospheric Physics
Nuclear Physics
Biophysics
Embedded Systems
Astronomy and Astrophysics.
The syllabus is really nicely planned and executed.
The best part is, it covers all the topics you need to strengthen for M.Sc entrances.
Hope it helps.
