Question

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

Answer 1

Answer:

Diamond.

Explanation:

Wavelength may be defined as the distance between two consecutive crest or trough of a wave. The S.I. unit of wavelength is meter.

Refractive index is inversely proportional to wavelength. The media with high refractive index has the shortest wavelength. Refractive index of ice is 1.31, refractive index of glass is 1.5, refractive index of water is 1.33 and refractive index of diamond is 2.4.Since, diamond has highest refractive index so it has shortest wavelength.

Thus, the correct answer is option (4).

Answer 2

Answer:

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.
