Which outcome occurs when a thin film's thickness approaches wavelengths of incident light?

💡 Explanation

Increased constructive interference occurs because path differences become significant relative to wavelengths; therefore, particular colours reflect strongly, rather than transmission, because other wavelengths might destructively interfere, cancelling out.
