Parallel light rays with a wavelength of 546 nm fall on a single slit. On a screen 1.75 m away, the distance between the first dark fringes on either side of the central maximum is 4.38 mm. What is the width of the slit? 0.436 mm 0.654 mm 0 0.872 mm 1.09 mm
A beam of light of wavelength 575 nm falls on a thin single slit 0.00325 mm wide. After the light passes through the slit. At what angle (measured from the original direction when viewed from the slit) will the 4th minimum (dark spot) occur? Give your answer to the nearest tenth (0.1) degree. Do not give units in your answer. Give only the positive angle (the one above the central maximum - not the negative angle below it).
The figure shows two spectra that overlap. It is not possible for the red end of one to overlap with the violet end of the other. True False
