i) Find the angular separation between the red hydrogen-α spectral line at 656 nm and the yellow sodium line at 589 nm if the two lines are observed in third order with a diffraction grating having 3 500 slits per cm. (Give the answer in degrees, correct to three significant figures.) [6]

(ii) Using the same diffraction grating as in (i) , what is the highest order that could possibly be observed using violet light of wavelength 420 nm?

Expert Solution

a)Angular separtion can be find using below formula

Here can be find using below formula

b)heigst order can be find using below formula

The maximum value of should not exceed 1.For m=7, value is greater than 1.Hence Heighst order Observed is,m=6 since value is less than 1

1: Under high resolution, the spectral line of Sodium (Z = 11) around 589 nm resolves into two lines at 589.5 nm and 588.9 nm due to spin-orbital coupling splitting the 1p shell into 2P3/2 and 2P1/2. Part A: Calculate the difference in energy between the 2P3/2 and 2P1/2 states. Part B: From this energy difference, estimate the magnitude of the internal magnetic field. Part C: If a magnetic field of 1 Tesla is applied to the Sodium atoms, the...

Emission lines from the hydrogen Hβ line (rest wavelength of 486.1 nm) are observed in the spectrum of a spiral galaxy at redshift z = 0.9. The galaxy's disk is observed to be inclined at an angle of 45 degrees to the line of sight. The central wavelength of the line is observed to be shifted by 0.5 nm to the red on one side of the galaxy, and by 0.5 nm to the blue on the other side of...
