Dear Babu, there are many Institutions that offer Distance Education for M.Sc in Phydics. There is no procedure as such. Now with everything being online, if you have any particular Institute in mind, you can check their official website, check their eligibility criteria and required documents. Institutions like IGNOU have the whole process online that you register, and upload the required documents and make the necessary payment. It is a different process with each Institution though. If you have any Institution in mind, do let us know and we shal help you with the process.
