Explanation / Answer

This is answered by analyzing the equation for the double slit

y/L = m(wavelength)/d

Part A)

You can see that y and L are directly proportional, so if the distance is increased, the distance between peaks is increased.

That is choice A

Part B)

In this case, you can see that y and d are inversely proportional, so if d is increased, the distance between peaks is decreased.

That is choice B
