Question:5 Two coherent mild resources are separated through 4 mm. If the 1/3 shiny fringe is discovered at an perspective of zero.02 radians, what is the wavelength of mild used? Question:6 In a double-slit test, if the gap between adjoining brilliant fringes is 0.5 mm and the gap to the display is 2 m, calculate the wavelength of light used. Question:7 A diffraction grating produces a 2nd-order maximum at an angle of 30 degrees for mild of wavelength 600 nm. What is the slit spacing of the grating? Question:8 Calculate the angle of diffraction for the primary-order maximum in a single- slit diffraction sample produced by way of light of wavelength 500 nm passing via a slit of width zero.1 mm.
