Problem

Four single-slit arrangements are listed below. For each, the screen distance is the same. Rank the arrangements from LARGEST to SMALLEST spacing between the center of the pattern and the first minimum. I. λ=700 nm,  a=0.10 mm\lambda=700\text{ nm},\;a=0.10\text{ mm} II. λ=500 nm,  a=0.05 mm\lambda=500\text{ nm},\;a=0.05\text{ mm} III. λ=600 nm,  a=0.08 mm\lambda=600\text{ nm},\;a=0.08\text{ mm} IV. λ=550 nm,  a=0.12 mm\lambda=550\text{ nm},\;a=0.12\text{ mm} a) I>III>IV>II\text{I} > \text{III} > \text{IV} > \text{II} b) IV>I>III>II\text{IV} > \text{I} > \text{III} > \text{II} c) II>III>I>IV\text{II} > \text{III} > \text{I} > \text{IV} d) III>II>I>IV\text{III} > \text{II} > \text{I} > \text{IV}
