Visible light of wavelength 566.7 nm is incident on a diffraction grating with d = 4,236 nm. At what angle, in degrees, with respect to the central maximum is the 5 order maximum observed? Please round your answer to one decimal place. Equation :dsind = ml
A diffraction grating with d = 2000 nm is used with a mercury discharge tube. Note that the wavelength of the blue-green light is 491.6 nm. What is the highest order line that can be seen for the blue green light using this diffraction grating? What is the value of the angle for this highest-order blue green line?
An intense monochromatic light incident on a diffraction grating with slit spacing d is causing an increase of the grating temperature. How should the frequency of the light be changed so that the position of bright fringes does not change. (Consider that the thermal expansion of the diffraction grating does not damage the slits.) Select one: a. f should be increased. b. f has no effect on the position of the bright fringes. c. f should be decreased. d. f...
2. You have a diffraction grating with 2500 lines/cm. You also have a light source that emits light at 2 different wavelengths, 540 nm and 690 nm, at the same time. The screen for your experiment is 1.2 meters from the diffraction grating. A. What is the line spacing for the grating? B. What is the difference in the angle of the 2nd bright fringe for each wavelength for this grating? C. Which wavelength is closer to the center of...
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...
a. How many lines per millimetre are required in a grating if the first-order diffraction line at 500 nm is to be observed at a reflection angle of 10 deg when the angle of incidence is 60 deg? I got 2080 line/mm for this part, which is the right answer! need help with part b b. What wavelength would have a second-order diffraction line at the same position as (a)? Your answer should have units of nanometers (nm).
