how does the diffraction peak width vary with the slith width?

how does the number of secondary maxima vary with slit width?

Expert Solution

A) Let the wavelength of the light used for diffraction be and the width of the slit be .

So, the central diffraction peak to occur we have the condition that,

For the angle theta very small we have

So the diffraction peak width,

So the width of the peaks increases for the small slit width and decreases for large slit width.

B) There are minima between two adjacent principal maxima there must be other maxima between two principal maxima. These are known as secondary maxima. So you can see the number of secondary maxima is not 'dependent on the slit width. In other words, we can say that varying the slit width we can vary the width and sharpness of the maximums but they will be eventually at the same place as they were before. So the no of secondary maxima does not vary with slits.

Width of Peak (cm): 1.6 Width of Slit for Single Peak: 2.3 The width of the center peak (w) can be calculated using the equation w = 2λL/ a where a is the width of the slit. Use this equation to determine the width of the slit that caused the diffraction pattern. Show your work. I am confused as to what I am finding since I do not have L. I have going backwards λL = 1.84. If someone could...

A single-slit diffraction pattern is formed on a distant screen. If the width of the single slit through which light passes is reduced, what happens to the width of the central bright fringe? Assume the angles involved remain small. The central bright fringe becomes wider. The central bright fringe remains the same size. The effect cannot be determined unless the distance between the slit and the screen is known. The central bright fringe becomes narrower.

A diffraction grating is made up of slits of width a with separation d. The grating is illuminated by monochromatic plane waves of wavelength λ at normal incidence. What is the angular width of a spectral line observed in the first order if the grating has N slits? State your answer in terms of the given variables. Δθw =

When running chromatography, one way to improve resolution and decrease peak width is by dropping the flow rate. a. Which variable in the van demter equation does this influence and how? (please explain and use descriptive names not just letter variable in the equation). b. when is this not an advantage? (please explain).
