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 18 μm, what was the width of the central maximum on the screen?

Explanation:

Given:

fibers diameter d= 18 μm

distance of the screen D= 30 cm

wavelength λ= 560 nm

we know that fringe width

putting values we get

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
