When diffraction of light occurs as it passes through

a slit, the angle to the minima $($dark spot$)$ in the

diffraction pattern is given by

a sin $=$ m$.$

For a minima of $4$ for a laser of $700$ nm that goes through a slit width of $0\mathrm{.}28$ mm$,$ find the angle in degrees $($to the nearest $100$th$).$

Now find $$x with the length of the tract from the slit to the screen being $95$cm$.($to the nearest $100$th$)$
