Error Checking Single Slit Diffraction Equation for Bright Lines

[donotremember]

I believe there are a number of errors in my physics correspondence course and I plan to include a page listing them when I write my final exam, but I would first like to make sure they are errors and not due to my lack of understanding.

1) "The coulomb is defined as the amount of charge passing any point in a circuit when a current of one Ampere is flowing."

I believe this should be

"The coulomb is defined as the amount of charge passing any point in a circuit when a current of one Ampere is flowing for a period of second."

2) For single slit diffraction the equation listed for finding bright lines other than the central one is

(n+ 1/2λ)/w

I believe this should be

(n+1/2)λ/wwhere n is the nth bright line λ; is the wavelength of the light and w is the slit width.

Your understanding is correct. The correspondence course is sloppy. Both of those statements are dimensionally wrong. The most fundamental sort of wrong.
