If a diffraction grating produces a third-order bright spot for red light of wavelength 700 nm, at 65° from the central maximum at what angle will the second order bright spot be for violet light of wavelength 400 nm? How many lines per mm on this grating? If a diffraction grating produces a third-order bright spot for red light of wavelength 700 nm, at 65° from the central maximum at what angle will the second order bright spot be for...
ASAP PLEASE The spacing of ruled lines on a diffraction grating is 1,845 nm. The grating is illuminated at normal incidence with a parallel beam of white light in the 395.5 nm to 700 nm wavelength band. The angular width of the gap between the first order spectrum and the second order spectrum is closest to (in degree):

Light source Observed line Grating Eye 4 Figure 9: Line Observed with Diffraction Grating DO NOT LOOK DIRECTLY AT THE LIGHT SOURCE. Use a meter stick to measure distances "a" and "x" in Figure 3. “x” is the distance from the emission tube (the source) to a line in the spectrum. One partner, the...
This lab uses the Fraunhofer diffraction formula to correlate the angle of diffraction with the wavelength it represents. n d sin In this equation, n is the grating order (here n = 1), the desired wavelength is ʎ and the grating spacing is d. For a 1000 line/mm grating (d = 1.0 x 10-6 m), orange light (ʎ = 589 nm) was diffracted at θ = 36o. Using the same grating, determine the diffraction angles of 482 nm,...
The hydrogen spectrum has a red line at 656 nm and a violet line at 434 nm. What angular separation between these two spectral lines is obtained with a diffraction grating that has 4014 lines/cm? (Assume that the light is incident normally on the grating.) 5.11 x first order separation Your incorrect answer may have resulted from roundoff error. Make sure you keep extra significant figures in intermediate steps of your calculation. 10.21 x second order By how many wavelengths...
3.

HE r yo he Г у will DIF deoslgby b) If the grating is illuminated with white light, how many maxima of the complete visible spectrum would be produced? White light ranges from 700 nm to 400 nm
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).
17. Red light of wavelength 7.00 x 10-7 m, incident normally on a diffraction grating, gave a first order maximum at an angle of 75°. Calculate the spacing of the diffraction grating.
