Suppose that you have a reflection diffraction grating with n= 140 lines per millimeter. Light from a sodium lamp passes through the grating and is diffracted onto a distant screen. a. Two visible lines in the sodium spectrum have wavelengths 498 nm and 569 nm. What is the angular separation Δθ of the first maxima of these spectral lines generated by this diffraction grating? answer is 57 degrees b. How wide does this grating need to be to allow you...

diagram please! 10. White light containing wavelengths from 400 nm to 750 nm strikes a grating containing 6,500 lines/cm. When viewed on a screen 1.5 m away, what is the distance along the screen between the second order maxima for the light at the red end of the spectrum and the third F. Chapter 26 the central maximum? Provide a rough sketch of the situation. (Diagram 3 pts.)
White light containing wavelengths from 400 nm to 750 nm falls on a grating with 7500 lines/cm. How wide is the first-order spectrum on a screen 2.20 m away? ___m
The spectrum of sodium has two closely spaced lines, known as the sodium doublet, with wavelengths 589.0 nm and 589.6 nm. When sodium light is incident on a diffraction grating with 4,300 rulings/cm, the maxima corresponding to this doublet are separated by Δy = 4.80 mm when the screen is L = 1.70 m from the grating. What is the value of m in this situation?
A diffraction grating is used in second order, to resolve the spectrum of the light emitted by a sodium lamp. The sodium light is known to contain a doublet (λ 1 589.00 nm and λ2-589.59 nm). The grating contains 500 lines per centimeter. What is the minimum size of the grating that must be illuminated by the collimated light in order to resolve the two spectral lines?

White light containing wavelengths from 4.10E2 nm to7.50E2 nm falls on a grating with 7.8E3 lines/cm. How wide is thefirst-order spectrum on a screen 2.70 m away? Enter scientific notation as 1.23E4.
White light containing wavelengths from 410 nm to 750 nm falls on a grating with 7500 slits/cm. How wide is the first-order spectrum on a screen 3.90 m away?
The spectrum of light from heated up Helium gas has only a few wavelengths present. These are known as spectral lines. It includes a strong yellow line with a wavelength in a vacuum of 587.5 nm and a red line at 667.8 nm. What are the angular separations (in degrees) between these two spectral lines for all visible orders obtained with a diffraction grating that has 7350 grooves/cm? (In this problem assume that the light is incident normally on the...
