Vedclass · Answer

(C) The Assertion is correct. The colour of the Morpho butterfly's wing is not due to pigments,but due to structural colouration caused by the interference of light reflected from the microscopic scales on the wing surface.When the wind moves the wing,the angle of incidence and the path difference between the light waves reflected from different layers of the scales change. This causes a shift in the interference pattern,resulting in a change in the observed colour.The Reason is incorrect because the colour is not caused by pigments,but by the physical structure of the wing surface (thin-film interference).Therefore,the correct option is $(C)$.

Assertion: At the first glance,the top surface of the Morpho butterfly's wing appears a beautiful blue-green. If the wind moves the colour changes.
Reason: Different pigments in the wing reflect light at different angles.
