Optics day one

FSM Independence day landed on Monday of optics week, putting Pohnpei Constitution Day on Friday (observed). This left only two days for optics, Wednesday and Thursday.

No mirror desk usage. The vegetable oil was a new addition. All demonstrations were done from the end of the table. This term marked the first time the beaker-in-beaker vegetable oil demonstration was done.  The inner beaker is a 100 ml beaker. Labels give away the existence of the inner beaker.  Reflection and refraction demonstrations as reflected onto the board.
