Coming soon
Astrophysics
This course will enable the students to –
1. To show how basic phyical principles can be applied to understand a variety of astrophysical objects and phenomena.
2. To study the physics of Celestial sphere, Basic stellar parameters, Optical telescopes, Sun, Solar system & Milkyway.
3. To enable the students to take up independently studies of astronomy and work further in Astro-physics.
