← ScienceWhich 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.
