For a single slit illuminated with a 500 nm light gives a diffraction pattern on a far screen,the angle  is mathematically given as

theta=25.3

Option A is correct

What angle does the 18th minimum occur?

Generally, the equation for the the angle   is mathematically given as

[tex]\theta=n(\lambda/d)[/tex]

Therefore

[tex]\theta 1/ \theta 2=n1(\lambda/d)/ n2(\lambda/d)[/tex]

In conclusion

theta/7=16/5

theta=10*7/5

theta=25.3
