The spindle motor speed can use one of two types of disk rotation methods: 1) constant linear velocity (CLV), used mainly in optical storage, varies the rotational speed of the optical disc depending upon the position of the head, and 2) constant angular velocity (CAV), used in HDDs, standard FDDs, a few optical disc systems, and vinyl audio ...
C = 1 / (2*π*f*Xc) = 1 / (2 * 3.141 * 60 * 127) = 21 μF. If the load also absorbs reactive power, capacitor bank must be increased in size to compensate. Prime mover speed should be used to generate frequency of 60 Hz: Typically, slip should be similar to full-load value when machine is running as motor, but negative (generator operation):
What can however be experimentally measured is the round-trip speed (or "two-way" speed of light) from the source to a mirror (or other method of reflection) and back again to detector. Albert Einstein chose a synchronization convention (see Einstein synchronization) that made the one-way speed equal to the two-way speed.
Slow light can also be achieved by exploiting the dispersion properties of planar waveguides realized with single negative metamaterials (SNM) [11] [12] or double negative metamaterials (DNM). [ 13 ] A predominant figure of merit [ clarification needed ] of slow light schemes is the bandwidth-delay product (BDP).
B. Wilson in 1750 [2] demonstrated the recoil force associated to the same corona discharge and precursor to the ion thruster was the corona discharge pinwheel. [3] The corona discharge from the freely rotating pinwheel arm with ends bent to sharp points [4] [5] gives the air a space charge, which repels the point because the polarity is the same for the point and the air.

Focal-plane shutters may also produce image distortion of very fast-moving objects or when panned rapidly, as described in the Rolling shutter article. A large relative difference between a slow wipe speed and a narrow curtain slit results in distortion because one side of the frame is exposed at a noticeably later instant than the other and the object's interim movement is imaged.
