← ScienceWhich effect results when reflections interfere constructively in fuel film measurement?
A)Enhanced signal intensity at that thickness✓
B)Reduced signal intensity at that thickness
C)Equilibrium thickness via mass balance
D)Uniform reflectivity across all thicknesses
💡 Explanation
Enhanced signal intensity occurs because constructive interference amplifies the reflected light at specific film thicknesses depending via optical path differences; therefore, intensity peaks rather than equilibrium thickness because film stability acts separately.
