A Monochromatic Light Of Wavelength 441nm Is Incident On A Narrow Slit On A Scre

A monochromatic light of wavelength 441nm is incident on a narrow slit,on a screen 2.00 m away,thedistance between the second diffraction minimum and the central maximum is 1.50cm,

a) calculate the angle of diffraction of the second minimum.

b) Find the width of the slit.
