Question

At \[\theta=0\], how do the distances from the secondary sources to point C compare?

Options

• Their distances increase with \[n\]

• Sources in the bottom half are always farther from C

• All secondary sources are at equal distances from C

• Sources in the top half are always farther from C

Answer 1

Point C lies on the normal, where \[\theta=0\]. At this point, all secondary sources are at equal distances from C.
