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.

Have you drawn a diagram?

Is 'theta' in your formula the angle for a maximum or for a minimum?

Singular: maximum, minimum
Plural: maxima, minima
