A nmnm argon-ion laser passes through a narrow
slit and the diffraction pattern is observed on a
screen mm away. On the viewing screen,
the distance between the centers of the second minima on either
side of the central bright fringe is mmmm.
Consider the angle θθ is small.

Problem 5 [6 points) For parts a) and b) of the below question, fill in the empty box with your answer (YOUR ANSWER MUST BE ONLY A NUMBER; DO NOT WRITE UNITS; DO NOT WRITE LETTERS). A 419 nm argon-ion laser passes through a narrow slit and the diffraction pattern is observed on a screen 5.698 m away. On the viewing screen, the distance between the centers of the second minima on either side of the central bright fringe is 44 mm. Consider the angle O is small. a) [1 point] Which formula can be used to calculate the location of a minima on the viewing screen? (refer to the formula sheet and select the number of the correct formula from the list) b) (5 points) Find the width of the slit. b = m
