As I understand it, electromagnetic waves have two components which are the result of each other, i.e., when
a moving electric charge creates a changing magnetic field at point X then a changing electric field is created at point Y
and this repeating process is what creates EM waves, so therefore, it requires no medium …
Do all waves have a medium?
No, mechanical waves
Do waves require medium?
These changing fields form electromagnetic waves. Electromagnetic waves differ from mechanical waves in that
they do not require a medium to propagate
. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
What are the 2 main types of waves?
Waves come in two kinds,
longitudinal and transverse
. Transverse waves are like those on water, with the surface going up and down, and longitudinal waves
What kind of waves require a medium to travel?
Mechanical waves
require a medium in order to transport their energy from one location to another. A sound wave is an example of a mechanical wave. Sound waves are incapable of traveling through a vacuum.
What are the 7 types of waves?
The electromagnetic spectrum includes, from longest wavelength to shortest:
radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays
. To tour the electromagnetic spectrum, follow the links below!
What are the classification of waves?
One way to categorize waves is on the basis of the direction of movement of the individual particles of the medium relative to the direction that the waves travel. Categorizing waves on this basis leads to three notable categories:
transverse waves
What are the 5 properties of waves?
There are many properties that scientists use to describe waves. They include
amplitude, frequency, period, wavelength, speed, and phase
.
What is a wave that does not require a medium?
Electromagnetic waves
differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
What are 4 types of waves?
- Microwaves.
- X-ray.
- Radio waves.
- Ultraviolet waves.
What is a medium in waves?
A medium is
a substance or material that can carry a wave
. The wave medium is not the wave and it does not make the wave; it merely carries or transports the wave from its source to other locations. The particles in a medium become disturbed and pass on this disturbance.
What is the most useful electromagnetic wave?
The different types of waves have different uses and functions in our everyday lives. The most important of these is
visible light
, which enables us to see. Radio waves have the longest wavelengths of all the electromagnetic waves. They range from around a foot long to several miles long.
What is the smallest electromagnetic wave?
Gamma Rays
-have the smallest wavelengths and the most energy of any other wave in the electromagnetic spectrum.
Which wave has the longest period?
The
wave with a frequency of 6 Hz
has the longest period. Period and frequency have an inverse relationship. thus, the wave with the lowest frequency has the longest period.
What are the 3 wave behaviors?
Reflection, refraction and diffraction
are all boundary behaviors of waves associated with the bending of the path of a wave. The bending of the path is an observable behavior when the medium is a two- or three-dimensional medium. Reflection occurs when there is a bouncing off of a barrier.
What are 4 basic properties of waves?
Examples of common waves that we come in contact with are sound and light. No matter whether you are talking about vibrations or waves, all of them can be characterized by the following four characteristics:
amplitude, wavelength, frequency, and speed
.
