You are working with an astronomy professor. He is quite excited about the August 2016 announcement of an Earth-like planet orbiting Proxima Centauri, 4.25 light- years from Earth. The equilibrium temperature of the planet is in a range in which liquid water can exist, offering the possibility of life evolving on this planet. Your professor is preparing a journal article on the expected characteristics of life forms that might inhabit this planet. In the example Thermal Radiation from Different Objects, we found that the peak in the radiation from a blackbody with the surface temperature of the Sun is in the middle of the range of wavelengths to which our eyes are sensitive. Assuming that is a general rule for evolution, determine for your professor the wavelength (in nm) that is in the middle of the range of wavelengths visible to any human-like aliens on the planet orbiting Proxima Centauri, which is a red dwarf with a surface temperature of 3,042 K. nm 4287
