A mоnоchrоmаtic lаser beаm illuminates a double-slit apparatus with a slit separation of 6×10-4 m. The interference pattern is formed on a screen that is 1.2 m away from the slits. If the distance between the eighth bright fringe and the second bright fringe on the screen is 6×10-3 m, what is the wavelength of the laser beam (measured in nm)?
A mоnоchrоmаtic lаser beаm with a wavelength of 720 nm illuminates a narrow slit with a width of 1 ×10-6 m. The resulting diffraction pattern is formed on a screen that is located at 1 m from the slit. What is the width of the pattern's central maximum (measured in m)?
