Early investigators (including Thomas Young) measured the thickness of wool fibers using diffraction. One early instrument used a collimated beam of 560 nm light to produce a diffraction pattern on a screen placed 30 cm from a single wool fiber.
Part A
If the fiber's diameter was 13 um, what was the width of the central maximum on the screen? Express your answer with the appropriate units.

Investigators measure the size of fog droplets using the diffraction of light. A camera records the diffraction pattern on a screen as the droplets pass in front of a laser, and a measurement of the size of the central maximum gives the droplet size. In one test, a 690 nm laser creates a pattern on a screen 30 cm from the droplets. Part A If the central maximum of the pattern is 0.32 cm in diameter, how large is the...
Quality control systems have been developed to remotely measure the diameter of wires using diffraction. A wire with a stated diameter of 170 μmblocks the beam of a 633 nm laser, producing a diffraction pattern on a screen 50.0 cm distant. The width of the central maximum is measured to be 3.77 mm. A) What is the diameter of the wire? a = ___ (value) ___ (units) B) The wire should have a diameter precisely within 1% of the stated...

) In the figure, a slit 0.30 mm wide is illuminated by light of wavelength 426 nm. A diffraction attern is seen on a screen 2.8 m from the slit. What is the linear distance on the screen between e first diffraction minima on either side of the central diffraction maximum? Answer: 8.0 mm 30) A thin beam of laser light of wavelength 514 nm passes through a diffraction grating having 3952 lines/cm. The resulting pattern is viewed on a...

If a viewing screen is located 2.4 m from the slits, find the distance (in meters) from the first dark fringe on one side of the central maximum to the second bright fringe on the other side (please read the problem carefully). Question 2 50 pts The spacing of ruled lines on a diffraction grating is 1,517 nm. The grating...
