Explanation:
The equation of grating is given by :
![(a+b)\ sin\theta=n\lambda](https://tex.z-dn.net/?f=%28a%2Bb%29%5C%20sin%5Ctheta%3Dn%5Clambda)
Here,
(a+b) is called grating element
N is the number of slits per unit length, ![N=\dfrac{1}{(a+b)}](https://tex.z-dn.net/?f=N%3D%5Cdfrac%7B1%7D%7B%28a%2Bb%29%7D)
n is the order
is the wavelength of light used
is the diffraction angle
Here, we need to write the effect on the interference pattern produced by a grating if the number of slits per unit length is increased. If the number of slits per unit length increases, the grating element decreases such that the angle of diffraction increases. Hence, the interference pattern shrinks.

Answer:
I would say all of the above.
Explanation:
Look below for more examples
<u>Increase the thickness of the wire</u> would decrease the resistance in a wire
Explanation:
Thicker wires have a larger cross-section that increases the surface area with which electrons can flow unimpeded. The thicker the wire, therefore, the lower the resistance.
Thin wires have very high resistance the reason the thin tungsten in a bulb glows because it is heated from the high resistance of many electrons trying to pass through a very small cross-section.
