回 1 of 1 a) A monochromic beam is incident on two slits, which results in the intensity pattern shown on screen a distance

L=4m

away (pic below where the envelope is drawn to help guide the eye). Let ' d '

=0.1mm

be the spacing between the two slits and 'a' be the width of the individual slits. Determine the wavelength of light and the slit width 'a'. b) A diffraction grating is illuminated with light of wavelength 650 nm and light of an unknown wavelength. The fourth-order maximum of the unknown wavelength exactly overlaps the third-order maximum of the 650 nm wavelength. What is the unknown wavelength?
