Discover the Maximum Wavelength of M101 Visible to the Naked Eye

In summary, the maximum wavelength of M101 is approximately 2.2 microns, measured using spectroscopy. This measurement is important for studying the galaxy's composition, temperature, age, and formation. The maximum wavelength is comparable to other spiral galaxies but can change over time due to factors such as aging stars and external interactions.

Do you mean longest wavelength? If so, that would be red (~700 nm). The H-alpha is the most intense emission line.

If you mean brightest wavelength, I haven't a clue.
