1. Light of wavelength 590nm falls on the wall with 2 slits 0.12 mm apart. A Photographic plate is placed at a distance L from the wall. The =3 maximum appears 18 cm from the central maximum on the photographic plate. How far is the plate from the wall?2. In a double slit experiment, determine an unknown wavelength of light, measured total distance between 16 maxima (8 on each side of the central maximum) is 16.8cm. The screen is located 3.45 m from the table slits, whose centers are 0.21 millimeter apart. What is the wavelength?3. He helium neon laser ( is 633 nm) illuminates a single slit and it is observed on a screen 1.5 m behind the slit. The distance between the 1st and the 2nd maxima in the diffraction pattern is 4.75 mm. What is the width (mm) of the slit?
