ASSESS The dark region at the top confirms our explanation: Here the
film is so thin that no visible wavelength undergoes constructive interference, so it appears dark. The film is probably about to break!

What if the traveling twin didnt turn around? Then the situation would be symmetric,
and each could argue that the others clocks run slow. But unless they get together again
at the same place, theres no unambiguous way to compare

and our spaceship is just one inertial reference frame. Well call that frame S9. Theres also
an accurate clock, C, in the spaceship, and C reads zero just as the light flash is emitted.
In Fig. 33.6a we consider the l

GOT IT? 32.3 Youre a biologist trying to resolve details of structures within a cell,
but they look fuzzy even at the highest power of your microscope. Which of the following
might help: (a) substituting an eyepiece with sho

protons, neutrons, nuclei, atoms, molecules, and solids? Is nature fundamentally
predictable, or does uncertainty rule in the microscopic worl
33.6 The Lorentz Transformations
What about y, z, and t? The y- and z-axes are perpendicular to the direction of motion,
so theres no length contraction and therefore y9 5 y and z9 5 z. The fact of time dilation
makes clear that measures of time diffe
