Which consequence results when surfactants reduce liquid surface tension?

A)Increased constructive thin-film interference
B)Decreased liquid refractive index
C)Reduced light scattering at interfaces
D)Enhanced molecular light absorption

💡 Explanation

Surfactants cause increased thin-film interference because a reduction in surface tension leads to thinner films; therefore, stronger constructive interference occurs due to maximized wave superposition from thinner interfaces, rather than reduced scattering at interfaces.
