It could measure the magnetic field amplitude and direction at spacecraft altitude with a spatial resolution of about when ambient Plasma (physics) disturbances are minimal.

The vector electric field amplitude defines both the intensity and the polarization of the light.

Electric fields contain electrical energy with energy density proportional to the square of the field amplitude.

If the field amplitude were continuous, the revival would have never happened at finite time.

The intensity profile is characterized by a single brilliant ring with a singularity at its center, where the field amplitude vanishes.

Indeed, when the electric field amplitude is low, the DNA really doesn't respond.

But, for a given frequency, there appears to be a critical electric field amplitude, above which the DNA rapidly collapses into a tight ball.

Both a and f are normalized dimensionless functions whose maximum value is 1, so that really represents the field amplitude.

The source intensity, which is the square of the field amplitude, is and the intensity at the screen .

The coefficient t is the ratio of the transmitted wave's electric field amplitude to that of the incident wave.
