The sodium D lines from a sodium lamp consist primarily of a doublet at 589.5 and 589.0 nm. Suppose we can obtain a grating with 500 lines/cm of any size we choose. How long (in cm) should the grating be required to separate the two sodium lines in the first order? Suppose the full length of the grating is illuminated.

Question
The sodium D lines from a sodium lamp consist primarily of a doublet at 589.5 and 589.0 nm. Suppose we can obtain a grating with 500 lines/cm of any size we choose. How long (in cm) should the grating be required to separate the two sodium lines in the first order? Suppose the full length of the grating is illuminated. Respond with the correct number of significant figures in scientific notation (Use E notation and only 1 digit before decimal e.g. 2.5E5 for 2.5 x 105) Type your numeric answer and submit 2.96E3 Hint R= lambda/Deta lambda=nLM N=1 for the strongest signals X You are incorrect
