The sky is blue because of Rayleigh scattering: smaller wavelengths of light scatter more in the atmosphere.

Why this is better
Body content already correctly used the 2.2x/5.9-6x figures per the 1/lambda^4 law, but the FAQ JSON-LD field still carried two stale numbers: the FAQ's summary answer said blue scatters '10 times' more than red (the unverified violet-vs-red figure misapplied to blue), and the Rayleigh-scattering definition answer said '5.5 times' instead of the correct ~5.9x. Both corrected to match the verified math and the fixed body text.
