In glass, light travels with a speed of 2.0 × 10^8 m/s. Light with a frequency of 3.6 × 10^14 Hz moves through the glass. What is the wavelength of the light?

Approximately in this glass.

Explanation:

The frequency of a wave is the number of periods that this wave completes per unit time.

The speed of a wave is the distance that this wave travels in unit time.

Thus, dividing the speed of the wave by the frequency of this wave would give the distance that this wave covers in each period (cycle) of this wave. By definition, the distance that a wave covers in each period is precisely the wavelength of this wave. Therefore, an equation for the wavelength of a wave would be:

The wavelength of this light in this glass would be:

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
