Crystal systems with `alpha=beta=gamma=90^(@)`-

In crystal system , alpha=beta=90^@,gamma=120^@ and a=1.5,b=1.5,c=3. Find the crystal?

The unit cell dimension of a particular crystal system is a=b=c, alpha=beta=gamma=90 , identifiy the crystal system.

For a crystal system, a=b=c, alpha=beta=gamma ne 90 , the system is

The axial angles in ......... crystal system are alpha ne beta ne gamma ne 90^(@) .

Which of the following crystal systems has unit cell with alpha=beta=90^(@),gamma=120^(@) (where alpha, betaandgamma are interfacial angles)-

(A) White tin is an example of tetragonal system. (R) For tetragonal system a=b=c and alpha=beta=gamma ne 90^(@) .

Consider the following statements, I. Possibe variations for a cubic crystal system is primitive only II. The axial angles of a hexagonal crystal system are alpha=beta=90^@ " and " gamma = 120^@ . Which of the above statements(s) is / are true ?

Assertion : Graphite is an example of tetragonal crystal system. Reason : For a tetragonal system, a=bnec,alpha=beta=90^(@),gamma=120^(@) .
