The best experiment to investigate the effects of wavelength on diffraction patterns is:
C Shine lasers of various colors at a narrow slit in an index card and measure the distance between the bright spots.
This experiment directly involves the concept of diffraction and allows you to observe how different wavelengths (colors) of light create different diffraction patterns, which can be analyzed by measuring the distance between the bright spots produced in the patterns.
