QUESTION: 10

A rotating calcite crystal is placed over an ink dot. On seeing through the crystal one finds:

Solution:

In calcite crystal there is a phenomenon of double refraction. So, we see one dot as a stationary object whereas the other being refracted at a little displaced position seems to be rotating about the first dot.
