← ScienceWhich optical consequence maximizes fringe visibility during thin-film interference?
A)Constructive interference minimizes overall reflection✓
B)Increased wavelengths diminish phase differences
C)Polarized emission minimizes stray reflections
D)High-intensity amplifies destructive effects
💡 Explanation
Constructive interference causes brighter fringes because waves add in phase while destructive interference results in minima; this **superposition** maximizes fringe contrast if it minimizes reflected light. Therefore, better visibility, rather than other intensities, due interference effects dependent on wavelength and reflection.
