Question

Into how many equal parts can the slit be divided to generalise the condition for minima?

Options

• \[2n\] equal parts

• \[n+\frac{1}{2}\] equal parts

• \[n\] equal parts

• \[\frac{n}{2}\] equal parts

Answer 1

The pairing argument can be generalised by dividing the slit into \[2n\] equal parts. This leads to minima at nonzero integer values of \[n\].
