A diffraction grating 2.5 cm wide produces a deviation of 42◦ in the second order peak with light of 550 nm wavelength. (a) What is the total number of lines on the grating? (b) If a screen is located at 1.8 m from the grating, where is the position of the first order maximum for that same wavelength? (c) For which wavelength the third order maximum overlaps with the second order maximum of 550 nm wavelength?
Alright Dude, If that worked for you... don't forget to give THUMBS
UP.(that will work for me!)
Please Vote...
If I missed something feel free to leave a comment.
atleast before giving down vote.
and, Thanks for using homeworklib- Smarter way to study.
