Wave Optics 321 (b) In the second order, . The second order images for the above wavelengths will be found at angles 2 m = ( ) [ ] 1 1 2 1 2 sin 2sin d sin θ λ θ = = m This yields: for 479 n λ = , 2 20.5 θ = ° ; for 647 nm λ = , 2 28.3 θ = ° ; and for 698 nm λ = , 2 30.7 θ = ° 24.36 (a) The longest wavelength in the visible spectrum is 700 nm, and the grating spacing is 3 6 1 mm 1.67 10 mm 1.67 10 m 600 d = = × = × Thus, ( ) 6 max 9 1.67 10 m sin90.0 sin90.0 2.38 700 10 m red d m λ × ° ° = = = × so 2 complete orders will be observed.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
