A monochromatic light of frequency Hz falls on eight slits separated from each other by 0.038 mm. What is the distance between the first-order and third-order maxima of the interference pattern produced on a screen that is 1.3 m from the slits?
Light of wavelength 500 nm falls normally on 50 slits that are mm wide and spaced mm apart. How many interference fringes lie in the central peak of the diffraction pattern?
Ten narrow slits are equally spaced 0.25 mm apart and illuminated with yellow light of wavelength 580 nm.
What is the angular position of the third principal maximum?
What is the angular position of the fourth principal maximum?
What is the separation of the third and fourth principal maxima on a screen 2.0 m from the slits?
