46) The central bright fringe in a single-split diffraction patternfrom light of wavelength 476 nm is 2.0 cm wide on a screen that is1.05 m from the slit. How wide is the slit ?
18) What slit separation would a grating have to produce afirst-order maximum at an angle of 40o for a wavelength of 589 nm ?
