(d) For diamond lattice:
Explanation:
If a positive test charge is placed in an electric field, it will exert the force in the test charge in the direction of electric field vector. We know that the direction of electric field is given by electric field lines. The field lines for a positive charge is outwards. The electric force acting on the charge is given by :
F = q E
Hence, this is the required solution.

This is called a<em> standing wave</em> since the waves don't move ALONG the rope. They just kind of stand in one place on the rope. if you just whip a long rope that's not tied to anything, you see the wave move along the rope, this is a TRANSVERSE wave. When you crack a qhip you send a transverse wave down the whip which concentrates in the tip, accelerating the tip to faster than the speed of sound resulting in a tiny sonic boom or "whip crack".
