In which media would light have the shortest wavelength ? ice ? glass ? water ? diamond

Diamond

Explanation:

As light moves from a less dense medium to a denser medium it slows down.

This is because the wave length of the light reduces. The denser the medium the less the wavelength. Diamond is the most dense solid among the provided choices thus light travelling through it has the least wavelength.

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
