How do our eyes use refraction? Light rays enter the eye through the cornea, the clear front “window” of the eye. The cornea’s refractive power bends the light rays in such a way that they pass freely through the pupil the opening in the center of the iris through which light enters the eye. The […]

Does fission increase mass?
Does fission increase mass? The products of fission are more stable, meaning that it is more difficult to split them apart. Since the binding energy per nucleon for fission products is higher, their total nucleonic mass is lower. The result of this higher binding energy and lower mass results in the production of energy. Why […]

What is Polar vs nonpolar?
What is Polar vs nonpolar? Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out. What is an example of a polar bond? Polar bonds are […]
