Which phenomenon is occurring when a person looks at a straight spoon in a glass
of water and the spoon appears bent?
a) reflection
b) prismatic reflectance
c) refraction
d) amplitude modification

Refraction is the answer because the spoon in the water is seen to be bent in the medium(water) and moving at a different speed.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
