No, EM waves are not charged. They are composed of electric and magnetic fields that oscillate perpendicular to each other and to the direction of propagation. These fields do not have an overall charge.
EM waves interact with charged particles through the electric and magnetic fields. When an EM wave encounters a charged particle, the electric field exerts a force on the particle, causing it to accelerate. This acceleration then generates its own electromagnetic radiation, leading to the interaction.
Yes, EM waves can be created by non-charged particles. This is because the electric and magnetic fields that make up EM waves do not require an overall charge to be present. For example, in the case of radio waves, the oscillation of electrons in a conducting antenna can generate EM waves.
Charged particles can affect the propagation of EM waves by absorbing, reflecting, or scattering them. This is because the electric and magnetic fields of EM waves interact with the charged particles, causing them to change direction or lose energy as they travel through a medium.
No, EM waves do not have a charge-to-mass ratio. This is because they are not composed of particles and do not have a rest mass. EM waves are a form of energy that can be described by their frequency, wavelength, and amplitude, but not by a charge-to-mass ratio.
