Ravina went to a gift shop on looking closely, she found many of the beverage glasses used for cold drinks had big thick glass walls. She decided not to buy these glasses, because she knows that this gives a false impression of more amount of liquid inside the glass. How does Ravina know about the false impression given by the beverage glasses made with very thick glass walls? What value associated to Ravina's decision?

Answer:

Being a Physics student, she knows that light rays from inside the glass (filled with liquid, denser) bends away from the normal and appear to diverge. So, it gives false impression that there is more amount of liquid in bottle. Honesty and humanitarian nature are values showed by Ravina.
