Final answer:

The order of light waves by wavelength from shortest to longest is blue, green, yellow, orange, red; the order by frequency from lowest to highest is red, orange, yellow, green, blue, due to their inverse relationship. The subtractive color wheel explains that the blue section looks blue as it reflects blue light, and the yellow section looks yellow by reflecting red and green light. Plant growth is affected by light color as chlorophyll absorbs blue and red light for photosynthesis more efficiently than green light.

Step-by-step explanation:

The question relates to the properties of light, particularly wavelength and frequency, as they apply to different colors of light. When organizing light waves by wavelength, the order from shortest to longest is blue, green, yellow, orange, red, with red having the longest wavelength. Part B of the question requires understanding that frequency is inversely related to wavelength; thus, the order from lowest to highest frequency is reversed: red, orange, yellow, green, blue, with blue having the highest frequency.

Considering the subtractive color wheel, colors appear based on the light they reflect. In part A of the question, the blue section of the wheel will look blue because this section reflects blue light and absorbs red and green. For part B, the yellow section of the wheel will look yellow because it reflects red and green light and absorbs blue.

In the context of plant growth under different colored lights, the plants that receive blue and red light will likely experience more growth compared to the one under green light. This is because chlorophyll, the pigment used in photosynthesis, absorbs blue and red light more efficiently than green light, which is mostly reflected by plants.
