Question

How is point P located in the single-slit experimental setup?

Options

• It is the midpoint of the slit

• It is a point within the slit of width \[a\]

• It is the point on the screen along the normal to the slit

• It is any point on the screen at angle \[\theta\] from the normal

Answer 1

P denotes any point on the screen at angle \[\theta\] from the normal. C, rather than P in general, is the point specifically along the normal.
