in many applications, including medical use and for
industrial development. He also explained to the
students the difference between 2D and 3d images formed
by light. The talk ended with an interactive session
between Prof. Boruah and the Physics students of USTM.
Earlier, welcoming the participants, Dr RK Sharma, Vice
