Question

what atmospheric interaction with radiation is responsible for blue skies and red sunsets?
a transmission
b reflection
c absorption
d scattering

Explanation:

Blue skies and red sunsets result from scattering (Rayleigh scattering). Shorter blue wavelengths scatter more in the atmosphere (blue sky), while longer red wavelengths scatter less at sunset, making skies red. Transmission, reflection, or absorption don’t explain this.

Answer:

D. Scattering
