- Homework Statement:
- What is the angular width between the second minima and second maxima on the same side of the central maxima if a wavelength of 650 nm passes through a slit of 3.0 x 10^-3m wide.
- Relevant Equations:
- sin theta = n(wavelength)/width
i feel like subbing the numbers into the equation isn't enough because of the second minima and maxima thing? not sure what to do... would appreciate any help.
