Dear student,
Find this solution, and RATE IT ,If you find it is helpful .your rating is very important to me.If any incorrectness ,kindly let me know I will rectify them soon.

    1-A parallel beam of light from a laser with a wavelength 450 nm, falls on a grating whose slits are 1.28 x 10-4 cm apart. How far (in cm) is the 1st order bright spot from the center of the pattern on a screen 3.4 m away? 2-A grating whose slits are 3.2x10-4 cm apart produces a third-order fringe at a 25.0° angle.

    An instructor wishes to determine the wavelength of the light in a laser beam. To do so, she directs the beam toward a partition with two tiny slits separated by 0.170 mm. An interference pattern appears on a screen that lies 5.10 m from the slit pair. The instructor's measurements show that two adjacent bright interference fringes lie 1.59 cm apart on the screen. What is the laser's wavelength (in nm) ?

    Two lasers are shining on a double slit, with slit separation d. Laser 1 has a wavelength of d/20, whereas laser 2 has a wavelength of d/15. The lasers produce separate interference patterns on a screen a distance 4.40 m away from the slits Coherent light with wavelength 600 nm passes through two very narrow slits, and the interference pattern is observed on a screen a distance of 3.00 m from the slits. The first-order bright fringe is a distance...
