There are too many happy coincidences that are not well set up, and the early sections
bounce back and forth between the two stories too frequently.
The spring-loaded targets
bounce back and forth on impact.
Now, Haroche and his colleagues have shown how to count photons nondestructively while they
bounce back and forth between two mirrors.
As the waves
bounce back and forth through the upper sand layer, waves of a certain frequency (number of vibrations per second) become amplified, or louder, explains Hunt.
Yet each system affects the design of the other, which means vehicle prototypes
bounce back and forth as we try to fix the problems caused by changes the other guy made in his system.
Bundles of sensors placed on each canal door emit signal alerts that
bounce back and forth between them.
Finally, in cyberspace we don't just have text, we have hypertext, and readers can
bounce back and forth between biblical texts, commentaries, and ancient maps, accessing an encyclopedia of resources at the touch of a keypad.
At each end of the stack, partially reflective crystal surfaces cause many of those photons to
bounce back and forth. The rebounding photons boost the odds that other electrons in the quantum wells also will convert their energy into photons rather than heat, Gmachl notes.
Once released, light photons
bounce back and forth between the laser tube's two mirrors (see diagram, upper left).
In fact, babies forced to
bounce back and forth between the sensory overload of the waking world and the sensory barrenness of dark, quiet bedrooms may often find it difficult to relax, fall asleep, wake up, or concentrate, she theorizes.
These ions
bounce back and forth in the tangled field, accelerating to energies high enough to emit X rays, Petre and Lisse suggest.
The photons emitted by excited atoms
bounce back and forth between two mirrors, inducing additional atoms to emit light of the same wavelength.
When surface electrons get stuck on a terrace, they
bounce back and forth between the edges in a standing wave; these electrons can still travel parallel to the edges, however.
