1. Mirages:
Mirage is a optical phenomenon which occurs due to total internal reflection.In hot summer days, we see the water on the roads but as we proceed towards it the water disappears.
2. Rainbow :
One of the wonderful phenomena observed in the sky in the form of Seven beautiful band of colours . It occurs due to:
-->Refraction.
--->Dispersion of light
--->total internal reflection.
3. Twinkling of stars :
Stars twinkle due o atmospheric refraction.
4. Lightning :
Lightning we observe during rainy days. It is one of the natural phenomena which occurs due to static electricity.
5. Advanced Sunrise and Delayed sunset :
It Occurs due to atmospheric refraction.
The sun is visible to us about 2 mins before the actual sunrise and about 2 minutes after the actual sunset because of atmospheric refraction.
