An x-ray are an example of electromagnetic radiation. They are highly energetic and are capable of ionizing most materials. This also makes them hazardous to human life; they can damage DNA molecules and cause cancer.
All electromagnetic waves are transverse (oscillation is transverse to the direction of motion).
Xray.
A radio wave is a kind of electromagnetic wave.
Ultraviolet is between those two.
I think it's a colorized Xray (think airport screening) of a broken vibrator.
Sound waves need a medium to propagate. Light-waves and other electromagnetic wave (radio, xray) do not.
Wavelengths
Speed is not a wave.
Electromagnetic wave.
A standing wave?
YES
The wave is called an electromagnetic wave.
a wave that the particles of the medium mover perpendicular to the direction the wave is traveling
