Mechanical vs Electromagnetic Waves
What do mechanical waves need to propagate?
to propagate, they need a material medium that can be gaseous, liquidor solid
what does the medium do?
A medium is a substance or material that carries the wave.
where do they occur?
They occur on the surface between two media, like water and air.
what is a transverse wave?
A wave in which the disturbance is perpendicular to the direction of propagation is called a transverse wave.
what is Rarefaction ?
Particles are spread out.
Qué necesitan las ondas electromagnéticas para propagarse?
they do not need a material medium to spread.
where do they travel?
he medium through which the wave travels is the stealth coils.
Example
The water rises and falls like transverse waves.
How is the amplitude?
the amplitude of the wave is perpendicular to the motion of that wave.
Compression?
Particles are close together.
What are mechanical waves?
It consists of the propagation of a vibrational disturbance inside an elastic material medium. Through it energy spreads.
what is energy
Energy, in physics,is the capacity for doing work.
What is it?
In physics, a surface wave is a mechanical wave that propagates along the interface between different media
what is the wavelength?
is the distance between peaks or between valleys of a wave.
who moves?
The medium moves parallel to the direction the waves are traveling.
What are electromagnetic waves?
They are the combination of waves in electric and magnetic fields produced by moving charges.
in what way can there be energy?
potential, kinetic, thermal, electrical, chemical, nuclear, or various other forms.
what does the crest do?
Crest - where the displacement of the medium is at a maximum
another definition of energy??
energy in the process of transferring from one body to another.
What is Trought and position of rest?
Trough – where the displacement of the medium is at a minimum, rest position where the medium shows no disturbance.
