The grommets on your shoe (Holes through which you place the lace) act as the pulley. When you tighten at the top it restricts at the bottom and compresses around your foot.
The same can be applied to a pulley; If you have the proper set up Pulling one string causes two actions; the first being the most obvious. And the second being its effect. The Grommets of your shoe are the pulley's; while your Shoelaces are just the rope with which you operate the pulley.
Answer:
(C) increase the distance between the slits in the diffraction grating
Explanation:
This light always form constructive interference, the difference in distance is given λn.
where;
λ is the wavelength
n is the nth maxima
At center fringe, n = 0; the difference is 0
for the first maximum, n= 1, the difference is λ
for second maximum, n = 2, the difference is 2λ
for third maximum, n = 3, the difference is 3λ
From the above illustrations, the wavelength is constant, but the distances between the slits increases, resulting in a higher difference.
Therefore, Option C is the correct answer: increase the distance between the slits in the diffraction grating
