Homework Statement
How wide is a single slit that gives its first minimum at 90°?
Homework Equations
øp=p(λ/a)
The Attempt at a Solution
Not quite sure what the answer is looking for but I'd guess I would need to solve for "a." So...
90°=(λ/a)
Is there any more information I can gather from this problem? Any guidance would be a big help.
Thanks guys!
