- 18. A laser beam is incident on a 400 lines per millimeter diffraction grating, The wavelength of the light produced by the laser is 670 nm and the interference pattern is obeerved on a screen that is 3.00 m from the grating. Determine the maximum mber of bright spots that can be obeerved. a) 4 b) 3 c) 8 d) 6 e) 7 that must be app8. How many (whole) bright fringes will be produced on an infinitely large screen if orange light (A = 590 nm) is incident on two slits that are 10.0 um apart?(The 3% margin of error does not apply for this question)- Violet light falls on two slits separated by 1.90 x 105 m. A first-order bright band appears 13.2 mm from the central bright band on a screen 0.600 m from the slits. What is λ?
- 3. A single slit in an opaque screen is illuminated with a He-Ne laser (A = 1.1522 µm), and on a distant screen it is found that the middle of the tenth dark fringe in the interference pattern lies at an angle 0 = 6.4° from the central maximum. What band of the EM spectrum does this wavelength of light belong to? (a) (b) What is the width of the slit? (b) (c) tween the slit and the distant screen is immersed in water (n = 1.33) rather than At what angle (in degrees) will this minimum appear if the region be- air? (c)2. If the light is replaced by another light with two wavelengths 700nm and 800nm. Is there any chance of overlapping of bright fringe by wavelength1 with bright fringe of wavelength of 2.11. Light of wavelength 520 nm is incident perpendicularly on a diffraction grating having 200 lines/mm. What is the highest order for which a sharp maximum occurs?

Find the highest-order brightfringe that will appear on the screen if the slit spacing is (a) 0.10mm and (b)10µm.1.) The distance between two slits in a double-slit experiment is 0.0016 mm. What is the angle between the central maximum and the second dark fringe in the interference pattern produced with light having a wavelength of 520 nm?- Light of wavelength 572 nm illuminates a single 0.77 mm wide slit.
