Why do EM waves not require a medium?
Both electrostatic fields and magnetic fields can influence objects in a vacuum, so EM waves (the combination of varying electromagnetic and electrostatic fields) have influence through a vacuum, that is, in the absence of a physical medium.
How is light damping achieved?
The amplitude of resonant oscillations can be reduced by damping.Light damping reduces oscillations slowly.Heavy damping reduces oscillations quickly.Critical damping stops the oscillation within one cycle.The graph above shows light damping.
What two kinds of fields make up an EM wave?
scalar field and vector field
Why is sharpness of resonance inversely proportional to the damping force?
the further the frequency from the resonant one, greater would be the damping effect, hence greater the sharpness the lowre is the damping effect
Why are damping devices used on machinery?
Damping is the resistance offered by a body when a system is in vibration. But the basic use of a damper(damping) is to help reduce the oscillations or vibrations.we can also conclude that we use damping to slow down the effect of a moving part.Damping controls the amplitude of vibrations just to avoid resonance conditions.

How is an EM wave produced?
By the interactions of Electric and Magnetic fields perpendicular to it.

What is negative damping?
It is the opposite of normal damping (oscillation decreases), so in negative damping to get even bigger oscillation.
Are there any soccer fields in Brazil?
God, yes. Lots and lots of 'em.

Is there any marijuana fields in rocky ford Colorado?
yup...try and find em
Applications of critical damping?
critical damping is when the amount of damping is large enough for the system to return toequilibrium as fast as possible without performing oscillations. Hope thatHELPED
What actors and actresses appeared in Em - 2007?
The cast of Em - 2007 includes: Adam Fawns as Joe Marneen Fields as Actress Amanda McErlean as Mother Karli McNamara as Em Kazuya Wright as himself
What two kinds of fields make up an EM wave?

What is the definition of viscous damping and viscous damping coefficient especially in Civil Engineering.?
== Answer }
What is geometric damping?
Geometric damping is also called radiation damping. It is defined as energy radiation into a surrounding medium. Damping is defined as energy dissipation property of structures and materials that are put through time-variable loading.
