This frequency shift is not a Doppler shift, but is rather an optical cavity resonance effect, as explained below in Ring lasers.
22.
Water slosh can significantly reduce the rebound height of a ball but some amounts of liquid seem to lead to a resonance effect.
23.
Digital pianos all have a similar pedal switch to hold notes in suspension, but only high-end models can reproduce the sympathetic resonance effect.
24.
When r = 0, the resonance effects for a particular reaction are no different from those for reaction of the unsubstituted reference compound.
25.
This resonance effect is caused by a feedback loop and is applied to drive the fundamental tones, octaves, 5th, 3rd to an infinite sustain.
26.
The bridge's spectacular destruction is often used as an object lesson in the necessity to consider both aerodynamics and resonance effects in civil and structural engineering.
27.
In reality EPR spectra have many different frequencies and not all of them can be exactly on resonance, therefore we need to take off-resonance effects into account.
28.
Many of the older colonial buildings have survived hundreds of years on the lakebed simply because they are not tall enough to be affected by the resonance effect.
29.
To harness the full power of the Helmholtz resonance effect, the opening of the intake valve must be timed correctly, otherwise the pulse could have a negative effect.
30.
The " virtual fan blades " appear semi-transparent and there are only 3 fat blades, versus 5 actual thinner fan blades, so some strange resonance effect is going on there.
