Question

• Based on our equation describing the locations of single-slit diffraction pattern minima , how should we vary each simulation parameter to reduce the angle θ at which we will find minima?

Select all that apply:

• Increase distance DD between the slit and the screen.

• Decrease distance DD between the slit and the screen.

• Distance DD between the slit and the screen does not matter.

• Increase the source's wavelength λ (make the light redder).

• Decrease the source's wavelength λ (make the light bluer).

• The source's wavelength λ does not matter.

• Increase the slit width aa.

• Decrease the slit width aa.

• The slit width aa does not matter.

Answer 1

we know that

a Sin = n

Also , Sin = y/D                        y = distance of the location of image from center ,

as D is increased, the value of Sin decrease and so does the angle

as source wavelength is decreased, the value of Sin decrease and so does the angle

as "a" is increased, the value of Sin decrease and so does the angle

Increase distance DD between the slit and the screen.

Decrease the source's wavelength λ (make the light bluer).

Increase the slit width a
