Question

Quizplus · Accepted Answer

The wavelengths of the visible spectrum, which fall in the range of 400-700 nm, would be most likely to be used by the planet's organisms. This is because this range of wavelengths provides the right amount of energy for biological processes and is also not absorbed by most substances, making it more useful for communication and sensing purposes. Additionally, many Earth organisms, like plants and some animals, have evolved to detect and use this range of wavelengths for survival, suggesting that it may be a common range for other forms of life as well.
