Question

explain why rainbow appears magenta in the front of the rainbow​

Answer 1

Answer:

For a rainbow to be seen, the sun must be behind an observer who is facing falling rain. Sunlight is refracted as it enters a raindrop, which causes the different wavelengths (colors) of visible light to separate. ... The reflected light is refracted as it exits the drop.

Answer 2

Answer:

$\huge\mathfrak\red{Answer}$

The reflected light is refracted as it exits the drop. Violet light (bending the most) emerges at an angle of 40 degrees relative to the incoming sunlight while red light (bending the least) exits the drop at an angle of 42 degrees. Other colors of the rainbow leave a raindrop at angles somewhere in between. According to Descartes' calculations using laws of optics, the three stage refraction-reflection-refraction pattern that light undergoes when passing through a raindrop produces a concentration of outgoing rays along a line that is 42 degrees above the head of an observer's shadow.
