Q1) Answer the following question :
A) Olivette is performing a diffraction experiment with a single slit. She measures the width of the central bright region on the screen to be 0.048 m. This is also, therefore, the distance between the first locations of destructive interference. How far is one of the regions of destructive interference from the center of the central bright region?
0.096 m
0.012 m
0.048 m
0.024 m
B) Jack thinks it would be cool to point the laser directly onto his open eye. Jack
did not read the warning in this lab document.
is a masochist.
has endangered his eyes.
has made all of the above at least conditionally true.
C) Olivette measures the distance from the single slit to the screen to be 0.200 m. She calculates that the distance from the first-order location of destructive interference to the center of the central bright fringe, y, is 0.002 m. What is the angle at which this location of destructive interference occurs? Express your answer in degrees.
D) Francine helped Olivette with her experiment and reminded her that the wavelength of the laser was 650 nm. Recall, Olivette measured the distance from the single slit to the screen to be 0.200 m. She also calculated that the distance from the first-order location of destructive interference to the center of the central bright fringe, y, is 0.002 m. Find the lateral width of the slit, as predicted by these measurements and given information. While you may find the answer in m, express your final answer in mm.
Explanation / Answer
The central bright fringe bisects the line of dark fringes. So the regions of destructive interference from the center of the central bright region is = 0.048/2 = 0.024m Option D is correct.
