Select the correct statement about rainbow., We can see a rainbow in the western sky in the late afternoon, The double rainbow has red on the inside and violet on the outside, A rainbow has an arc shape, since the earth is round, A rainbow on the moon is violet on the inside and red on the outside

MARKS App · Accepted Answer

In late afternoon rainbow is visible in east side when light of sun in west side is reflected and refracted by a layer of water droplets. Rainbow is circular because locous of reflected rays reaching eye of observer is a circle. Its roundness is not due to roundness of earth. There is no rainbow on moon due to lack of atmosphere. In case of a primary rainbow, violet colour is on inside and red colour is on outside of arc. In case of a secondary rainbow, red colour is on inside and violet colour is on outside of arc. So, none of the option is correct. Option ( b ) is correct, if only secondary rainbow is considered.
