Question

what are observation and conclusion take half glass of water Dip a spoon in it

Answer 1

Answer:

You know this from the spoon-in-a-glass trick: if you put a spoon in a glass of water, you notice that the handle of the spoon makes an abrupt "break" at the water/air interface. The same happens as light enters a piece of ice: it will bend. ... However, most of the light penetrates the crystal and is bent, or refracted.
