Sun’s halo is produced by the refraction of light in:
- Water vapour, in Stratus clouds
- Ice crystals in Cirrocumulus clouds
- Ice crystals in Cirrus clouds
- Dust particles in Stratus clouds
Explanation
Option (c) is correct
- A solar halo is an optical phenomenon formed due to the refraction and reflection of sunlight through hexagonal ice crystals present in high-altitude Cirrus clouds. These clouds occur in the upper troposphere and produce ring-like halos around the Sun or Moon.
