What is the linear width of the central maximum

Reference no: EM13256862

A lens that is "optically perfect" is still limited by diffraction effects. Suppose a lens has a diameter of 130mm and a focal length of 650mm .

A. Find the angular width (that is, the angle from the bottom to the top) of the central maximum in the diffraction pattern formed by this lens when illuminated with 510 nm light.

b. What is the linear width (diameter) of the central maximum at the focal distance of the lens?
