Assertion (A) : A secondary rainbow have inverted colours than the primary rainbow
Reason (R) : The secondary rainbow is formed by single total internal reflection
 

In a secondary rainbow, the order of colors is reversed, with red on the inner edge and violet on the outer edge. This reversal of colors occurs because the light that creates a secondary rainbow undergoes two internal reflections within the water droplets, which causes a more complex dispersion of light. The secondary rainbow is also typically fainter than the primary rainbow due to the additional reflections and is located at a larger angle (about 50-53 degrees) from the anti-solar point, which is the point in the sky directly opposite the sun.
