Assertion : Graphite is an example of tetragonal crystal system. Reason : For a tetragonal system , a = b is not equal to c, alpha = bita = 90 degree, gama = 120 degree a = b is not equal to c alpha = bita = 90 degree Assertion : Graphite is an example of tetragonal crystal system. Reason : For a tetragonal system gama = 120 degree February 8, 2021 Category: Uncategorised (JEE Advanced Physics by BM Sharma + GMP Solutions) , Facebook Messenger WhatsApp Share this:TwitterFacebook Related
