So, I’m assuming that we’re treating light as a propagating wave.
Amplitude measures the amount of energy transported by a wave, thus amplitude squared is directly proportional to the light’s energy. The higher the amplitude, the higher the energy.
Energy is also directly proportional to the frequency of a wave, the higher the frequency, the higher the energy.
I took my second answer from the formula below:
E=cf
A stationary charge is located between the poles of a horseshoe magnet. The magnetic force exerted by the charge is zero.
<h3>What is charge?</h3>
Charge is the physical property of matter which cause a particle to attract or repel when placed in its field.
A stationary charged particle does not interact with a static magnetic field. A charge placed in a magnetic field experiences a magnetic force. There will be no magnetic force acting on a stationary charge. The charge must be moving in order to have magnetic force on it.
Thus, the magnetic force exerted by the charge is zero.
