How far is the screen from the lens

Reference no: EM13267985

A plane wave of wavelength 580 nm is incident on a slit with a width of a = 0.50 mm. A thin converging lens of focal length +80 cm is placed between the slit and a viewing screen and focuses the light on the screen.

(a) How far is the screen from the lens?

(b) What is the distance on the screen from the center of the diffraction pattern to the first minimum?
