Optics Workshops at Chaya Someswara Swamy Temple

Optics Workshop at Chaya Someswara Swamy Temple The workshop objective is to enjoy and understand optics. You can see the workshop report here.


Workshop is designed for Physical Science teachers and class 10th students. We can accomodate 40 students and 10 teachers. The teachers can contact CV Hari Krishna or GLN Murthy. Students are to be nominated by teachers themselves, preferably 4 students per schools. NAEST 2017 Mains qualifiers are also invited to register themselves.
