Three double-slit experiments are performed, each with the same screen distance

L

. • Experiment I uses light of wavelength

600\,\text{nm}

and slits separated by

0.30\,\text{mm}

. • Experiment II uses light of wavelength

500\,\text{nm}

and slits separated by

0.20\,\text{mm}

. • Experiment III uses light of wavelength

700\,\text{nm}

and slits separated by

0.40\,\text{mm}

. Rank the experiments by the distance between adjacent bright fringes, from largest to smallest. (a) III
