Statement I is true; it is possible to see a secondary rainbow outside the primary one. The secondary rainbow is less intense and typically appears about 10 degrees wider than the primary bow, with the colours reversed. Statement II is false; the secondary rainbow is formed by sunlight undergoing *two* internal reflections inside the water droplets before refracting out. The primary rainbow is formed by a single internal reflection.
A secondary rainbow results from two internal reflections of light within raindrops, not one reflection followed by refraction.
The order of colours in the primary rainbow (red on the outside, violet on the inside) is reversed in the secondary rainbow (violet on the outside, red on the inside) due to the extra internal reflection.
