A tuning fork has a frequency of 400 Hz and hence a period of 2.50 × 10−3 s.If the tuning fork is in an inertial frame of reference moving by the observer at speed of 0.680c,what is the frequency of the fork as measured by the observer? (Assume that measurements are strictly by optical means and that the speed of sound waves in air is not pertinent here. )
Membrane Potential
The electric potential difference across a cell's plasma membrane, crucial for the transmission of nerve impulses and muscle contraction.
Local Potential
A reversible, localized change in the electrical potential of a neuron's membrane, which can lead to an action potential if a certain threshold is reached.
Depolarization
A reduction in the difference in electric charge across a cell membrane, which is essential for generating action potentials in neurons and muscle cells.
Repolarization
The process of restoring the negative charge inside the cell membrane after a depolarization event.
