Due to multiple refractions and reflections.

Vedclass · Answer

(A) secondary rainbow is formed by two internal reflections and two refractions of sunlight within the water droplets. Each reflection results in a significant loss of light intensity because a portion of the light is transmitted out of the droplet instead of being reflected. Since the secondary rainbow involves two such reflections,the cumulative loss of light energy is greater than that in a primary rainbow,which involves only one internal reflection. Therefore,the intensity of light in a secondary rainbow is significantly lower.
