Optical Physics Notes

1. Dark Asphalt Albedo: Standard airport runway asphalt has a reflectance of merely 0.08 to 0.14. Unlike light concrete or marble, tarmac fails to bounce fill-light under the hairline, exaggerating under-hang shadows by up to 300%.

2. Rayleigh Diffusion in Overcast Clouds: Thick cloud decks shift ambient color temperature from 5200K (warm solar yellow) to 6800K–7500K (cool sky blue). Yellow pheomelanin pigment cancels with blue skylight, muting warm tones into cooler muddy umber.

3. Refractive Index of Hair Keratin: Wet or product-heavy hair reduces diffuse surface scattering by index-matching the cuticle scales (n=1.55), plunging apparent lightness (L*) dramatically even without adding dark melanin dye.
