Question

Wh we see rainbow colours in bubbles

Answer 1

Its due to dispertion of light and
it means that when light passes through a medium, it gives a series of VIBGYOR coloures light so we see those colours in bubbles.This means that, even if the soap film is of uniform thickness, different colors canbe seen. Light entering thebubble directly travels a shorter path than light entering at a wider angle. This allows different wavelengths to undergo constructive and destructive interference, sodifferent colors are perceived.
