7)The visible light portion of the electromagnetic spectrum of light is often subdivided into the colors of red, orange, yellow, green, blue, indigo, and violet (sometimes referred to as ROY G BIV. Using the words greatest, least, highest, lowest, fastest, slowest, longest and shortest, write a sentence of two that describes how light at the red end of the visible portion of the spectrum and light at the violet end of the visible light portion of the spectrum compare in terms of energy, frequency, speed and wavelength.

Explanation:

When it comes to visible light, the highest frequency color, is violet and also has the most energy.

The lowest frequency of visible light is red, has the least energy.

Violet has the shortest wavelength, at around 380 nanometers,

red has the longest wavelength, at around 700 nanometers.

Since red has a larger wavelength, it has a smaller refractive index. This means that red has the largest speed in the visible spectrum and violet the lowest.
