Oh, movie is one, the second I would want to share is the real experience of seeing a real Echoes of Rainbow today. It was a double rainbow, where a dim secondary rainbow is seen outside the primary bow. According to WIKIPEDIA, secondary rainbows are caused by a double reflection of sunlight inside the raindrops, and appear at an angle of 50°–53°. As a result of the second reflection, the colours of a secondary rainbow are inverted compared to the primary bow, with blue on the outside and red on the inside. The secondary rainbow is fainter than the primary because more light escapes from two reflections compared to one and because the rainbow itself is spread over a greater area of the sky. The dark area of unlit sky lying between the primary and secondary bows is called Alexander's band, after Alexander of Aphrodisias who first described it.
大哥 told Flora that double rainbow is a very rare phenomenon. But I am lucky to be able to watch it together with two friends today. That strengthen my believe of miracles do happen. They really do.
Share some photos of double rainbows here, though the image quality is not good, you'd be able to see if look carefully.
These photos were taken while on the home at MRR2. Some motorists stopped at the road bank to take pictures eventhough it was raining~
