ORIGINAL PROBLEM STATEMENT

The original problem statement given by clientAroon Giriyapur Sir is to design creative andengaging experiment for physics labs using

Mechatronics based approach system by usingmodern sensing, instrumentation and dataacquisition tools along with a user friendlyGraphical User Interface (GUI) for data analysis

and plotting.

The problem statement can be given asTo demonstrate the laws of reflection & refraction
