hello gagan Arora

I hope you are doing good.  If i m interpreting your question right , then i will tell you their is no masters course is offered by du for particular field of physics . You have to go for masters of physics where you have to do analysis and research projects and then select the specialised field in which you have keen interest in like kinematics, electomagentism, molecular physics,etc . and then try to make projects on it

Hope you found this answer helpful. Good luck for your future
