Muscle contractions change striation distances from 1.87 to 1.94 micrometers. These changes are measured by shining a beam of laser light with a wavelength of 650 nm onto a tank of freshwater containing glass catfish. The diffraction pattern is directed onto a screen that is 30cm behind the fish. Investigators measured the change in the location of the m=1 diffraction spot as the fish swam in front of the beam. What is the distance that the diffraction spot moved on the screen?
