Final answer:
The frequency of blue light is greater than that of green light due to its shorter wavelength. This also implies that blue light has more energy than green light. Considering their properties, blue light would be the most effective for plant growth using chlorophyll a and b.
Step-by-step explanation:
The frequency of blue light is greater than that of green light. This can be understood by considering the electromagnetic spectrum, where light is arranged according to its wavelength and frequency. Blue light has a shorter wavelength than green light, and since the speed of light is constant in a vacuum, a shorter wavelength corresponds to a higher frequency. Given this relationship, we can ascertain that blue light has more energy than green light as well.
To answer some related concepts: if "light C" has a shorter wavelength than "light D", then "light C" has a larger energy than "light D". Similarly, if "light E" has a higher frequency than "light F", then "light E" has a shorter wavelength than "light F". For plant growth under different colored lights using chlorophyll a and b, blue light typically supports better photosynthetic efficiency, so we might predict plant A, grown under blue light, to exhibit the most growth.
