Light Scattering

Why the sky look blue during midday and red during sunset

• Reflection of light

• Refraction of light

• Dispersion of Light

• Scattering of Light

Why does scattering of light occur?

• Light rays are blocked and reflected to all directions by the clouds or particles in the air

• Light rays are blocked and reflracted to all directions by the clouds or particles in the air

• Light rays are passing through and refracted to all directions by the clouds or particles in the air
