Are the features visible in the spectrum of a diffraction grating resulting from interference or diffraction? Explain your answer. What aspect of the spectrum can be attributed to diffraction (as in "single-slit diffraction")?
Are the features visible in the spectrum of a diffraction grating resulting from interference or diffraction?...
Visible light passes through a diffraction grating that has 900 slits per centimeter, and the interference pattern is observed on a screen that is 2.32 m from the grating. Part A In the first-order spectrum, maxima for two different wavelengths are separated on the screen by 3.24 mm. What is the difference between these wavelengths? Express your answer in meters.

1. Explain single slit diffraction? What is Fraunhoffer diffraction? Describe diffraction grating and its use in CD tracking? Calculate the single slit width (a) for a destructive interference that occurs in case of single slit diffraction with dark = 100, m=+2, and 2 = 740 nm? 2. Describe principle, construction of reflecting telescope? What is limiting condition of resolution or Rayleigh's criterion?
A diffraction grating has 755 slits/mm. What is the highest order that contains the entire visible spectrum? (The wavelength range of the visible spectrum is approximately 400-700 nm.)
Sunlight is incident on a diffraction grating that has 3,350 lines/cm. The second-order spectrum over the visible range (400-700 nm) is to be limited to 1.50 cm along a screen that is a distance L from the grating. What is the required value of L? [answer] cm

The atomic emission spectrum of a light source is analyzed with a diffraction grating. A thick line near 589.0 nm is observed. In order to resolve the thick line into two fine lines in first order, you replace with a 2.450 cm long diffraction grating, and you barely observed two distinct first order spectral lines at 589.0 and 589.6 nm on a screen 5.000 m away. a. What is the resolving power of the grating? b. What is the slit...
Why can you superimpose Single Slit Diffraction and Multiple Slit Interference patterns? To get the light curve, bands from multiple slit interference are superimposed upon single slit diffraction pattern. Why? I need help understanding this concept.
beam of electrons is shot through a diffraction grating with 10,000 lines per centimeter. interference pattern on a detector is distance L= 0.3500 m from the thin slits. central maximum width= 1.45 x 10^-6 m. draw a diagram with slits, detector, L, W, and also angular position (theta) of first order minimum in 2 slit interference pattern. find theta, wavelength of electrons in meters, and if you doubled the number of lines per cm, what would happen to the width?
35. A grating has 400 lines/mm. How many orders of the entire visible spectrum (400-700 nm) can it produce in a diffraction ex- periment, in addition to the m 0 order? ssm Ilw
11. A diffraction grating (multiple slits) with 3500 slits/em is illuminated with white light at normal incidence. The distance between the grating and the screen is 1.2 m. What is the gap on the screen between the first order visible spectrum and second order visible spectrum? 7% [Note that the angle between the central line and the line to the spectrum on the screen is not small] Answer:
