What is mean by Eletromagnetic waves?
The waves which have both properties as that of electricity & magnet.
What do the light waves travel more when they enter in water?
eletromagnetic waves
Eletromagnetic energy traveling in transverse waves is?
That is called an electromagnetic wave.
Is a water wave a electromagnetic?
No, eletromagnetic waves propagate in two planes (eletro-magnetic) and can propagate in a vacuum. Water waves, on the other hand, are dependant on matter to transfer energy, making it a mechanical wave, not an eletromagnetic one.
How are sound waves and eletromagnetic waves different?
Sound waves require a medium such as air, solid, or liquid in order to propagate. Electromagnetic waves do not require a medium for propagation and can move through a vacuum.
Is a water wave an electromagnetic wave?
No, eletromagnetic waves propagate in two planes (eletro-magnetic) and can propagate in a vacuum. Water waves, on the other hand, are dependant on matter to transfer energy, making it a mechanical wave, not an eletromagnetic one.
What waves are used in MRI machine?
Both magnetic- and radio-waves.
Which of the following waves does not require a medium through which to travel?
Any eletromagnetic wave. Light, visible or non visible.
How do crest and trough relate to compression and rarefaction?
They don't. They only relate to transverse waves, not longitudinal waves.
How does the Doppler effect relate to waves?
It only works with waves.
Will a MRI work without a magnet?
No. Put simply, an MRI scanner utilised radio waves and a magnetic field. Without a magnet, there is no magnetic resonance imaging (MRI).
What waves do MRI's use?
MRI uses magnetic fields and radio waves to measures how much water is in different tissues of the body, maps the location of the water and then uses this information to generate a detailed image.
