what are electromagnetic wave?
The range of frequencies and wavelengths that make up all forms of electromagnetic radiation
wavelengths that depends on the nuclear energy
waves that are created as a result of vibrations between an electric field and a magnetic field.
wavelengths that made up by the human
what kind of energy that is carried by an electromagnetic wave?
solar energy
mechanical energy
electromagnetic spectrum
electromagnetic radiation
choose two of the different types of EM wave
what does Antenna creates?
produces an oscillating potential difference
creates electromagnetic wave that propagate through the air
changing magnetic field generated by the changing of electric field
How electromagnetic waves travel?
travel through the matter other than air
through the vibration of water particles
through the surface of the earth
why do modulator use data?
increase the potential difference of the resulting signal
to change the carrier waves amplitude or frequency
in which direction does the EMF recharges the capacitor?
inverse
upward
downward
reverse

electrons within atoms
atoms
when does quartz crystal deform?
when the application of AC potential difference cut section quartz
when the potential difference is applied across them
when will acceleration become largest?
when the antenna is accelerated to the direction of the waves
when the antenna is disappears
