Single Slit Diffraction light intensity

Click For Summary
SUMMARY

The discussion focuses on the light intensity pattern produced by single slit diffraction, specifically analyzing the width of the central maximum based on the slit width. The equation w=(2λL)/a is critical, where w represents the width of the central maximum, λ is the wavelength of light, L is the distance to the viewing screen, and a is the slit width. Participants conclude that a broader slit results in a narrower central maximum, while a narrower slit produces a broader central maximum, confirming the inverse relationship between slit width and central maximum width.

Homework Statement



This is the light intensity on a viewing screen behind a rectangular opening in a screen. Is the shape of the opening (1), (2), or (3)?

Homework Equations



w=(2λL)/a

where w is the width of the central maximum, L is the distance to the viewing screen, and a is the width of the slit.

The Attempt at a Solution



I'm inclined to say (1) ... The first image. I don't know how to justify this assumption, though.

I don't think the equation above can help me because none of the variables were given in the problem statement... So this is more of a qualitative question I presume.

When do you see broader central maximum, with a broader slit or with a narrower slit?
