An n-slit system has slit separation d and slit width a. plane waves with intensity i and wavelength o are incident normally on it. the angular separation of the lines depends only on:

a. a and n. b. i and n. c. n and o. d. a and o. e. d and o

E. d and O

Explanation:

"Light passing through a single slit forms a diffraction pattern somewhat different from those formed by double slits or diffraction gratings".

According to Huygens’s principle, "for each element of the wavefront in the slit emits wavelets. These are like rays that start out in phase and head in all directions. (Each ray is perpendicular to the wavefront of a wavelet.) Assuming the screen is very far away compared with the size of the slit, rays heading toward a common destination are nearly parallel".

The destructive interference for a single slit is given by:

Where

d is the slit width

is the light's wavelength

is the angle relative to the original direction of the light

m is the order od the minimum

I represent the intensity

When the intensity and the wavelength are incident normally the angular as we can see on the expression above the angular separation just depends of the distance d and the wavelength O.

i'm so sorry if this is wrong i'm only in 6th grade xd
