The chart shows the speed at which light travels through different media. A 2 column by 5 row table. Column 1 is titled Medium a

nd contains the following entries: Water, Air, Glass, Diamond. Column 2 is titled Speed of Light (meters per second) and contains the following entries: 2.25 times 10 Superscript 8 baseline, 2.99 times 10 Superscript 8 baseline, 1.97 times 10 Superscript 8 baseline, 1.24 times 10 Superscript 8 baseline. In which medium would light have the longest wavelength? water air glass diamond

The medium whose light have the longest wavelength is air.

<h3>What is wavelength?</h3>

The wavelength is the distance between the adjacent crest or trough of the sinusoidal wave. The wavelength is the reciprocal of the frequency of the wave.

Wavelength λ = v/f

where v is the speed of wave in medium.

Given is the chart shows the speed at which light travels through different media.

Medium Speed of light in m/s

Water 2.25 x 10⁸

Air 2.99 x 10⁸

Glass 1.97 x 10⁸

Diamond 1.24 x 10⁸

The speed of light is directly proportional to the wavelength. Greater the speed, greater will be the wavelength.

From the chart, air has the highest speed of light.

Thus, the medium whose light have the longest wavelength is air.
