Question

Jobi read in his science textbook that when a laser is shined into a diamond in a dark room, the diamond will scatter the light, throwing many separate, focused beams of light on the walls and ceiling. Jobi hypothesized that any clear, cut stone would have the same effect on a laser. He collected samples of quartz and tried it out, but the quartz did not have the same effect.
Jobi decided that his hypothesis and experiment were a waste. Was Jobi correct about this?
