Problem
A beam of 500 nm light passes through a pair of slits separated by 0.40 mm. For the first-order maximum, calculate the percentage difference between θ (in radians) and sin θ. Report the percentage to two significant figures and indicate whether the small-angle approximation would be considered acceptable if an error below 1.0 % is required.
