What is the other name for electromagnetic waves?
Electromagnetic waves of different frequency are called by different names since they have different sources and effects on matter. In order of increasing frequency and decreasing wavelength these are: radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays and gamma rays.
What are the terms of electromagnetic waves?
DESCRIBING ELECTROMAGNETIC ENERGY Radio and microwaves are usually described in terms of frequency (Hertz), infrared and visible light in terms of wavelength (meters), and x-rays and gamma rays in terms of energy (electron volts).
Are electromagnetic waves longitudinal or transverse?
Electromagnetic waves are transverse waves. That means the electric and magnetic fields change (oscillate) in a plane that is perpendicular to the direction of propagation of the wave. Also note that electric and magnetic fields in an EM wave are also perpendicular to each other.
What is the other name for longitudinal wave?
physics. Alternate titles: compression wave, compressional wave, pressure wave, rarefaction wave.
What is another word for electromagnetic energy?
Hypernym for Electromagnetic radiation: electron beam, actinic ray, beam, x-radiation, radio emission, ray, gamma ray, gamma radiation, black-body radiation, radio wave, x-ray, roentgen ray, blackbody radiation, actinic radiation, microwave, line, x ray, radio radiation.
What is an electromagnetic wave simple definition?
Definition of electromagnetic wave : one of the waves that are propagated by simultaneous periodic variations of electric and magnetic field intensity and that include radio waves, infrared, visible light, ultraviolet, X-rays, and gamma rays.
How are mechanical waves and electromagnetic waves different?
Electromagnetic waves can travel through a vacuum, that is an empty space, whereas mechanical waves cannot. They need a medium to travel such as water or air. Ripples in a pond are an example of mechanical waves whereas electromagnetic waves include light and radio signals, which can travel through the vacuum of space.
What are types of mechanical waves?
There are two basic types of wave motion for mechanical waves: longitudinal waves and transverse waves.
What waves are longitudinal?
Examples of longitudinal waves include:
- sound waves.
- ultrasound waves.
- seismic P-waves.
What is transverse wave and longitudinal wave?
Transverse waves cause the medium to move perpendicular to the direction of the wave. Longitudinal waves cause the medium to move parallel to the direction of the wave.
What is the meaning of electromagnetic energy?
Electromagnetic energy is a term used to describe all the different kinds of energies released into space by stars such as the Sun. These kinds of energies include some that you will recognize and some that will sound strange. They include: Radio Waves. TV waves.
What type of waves are electromagnetic waves?
Electromagnetic waves are transverse waves. That means the electric and magnetic fields change (oscillate) in a plane that is perpendicular to the direction of propagation of the wave. Also note that electric and magnetic fields in an EM wave are also perpendicular to each other.
What is the direction of E x b in electromagnetic waves?
E is the electric field vector, and B is the magnetic field vector of the EM wave. For electromagnetic waves E and B are always perpendicular to each other and perpendicular to the direction of propagation. The direction of propagation is the direction of E x B.
What is a transverse wave called?
Transverse waves A wave is called a transverse wave when the disturbances in the wave are perpendicular (at right angles) to the direction of propagation of the wave. Electromagnetic waves are transverse waves.
How do electromagnetic waves travel through an antenna?
Electromagnetic waves the EM wave propagates because the electric field recreates the magnetic field and the magnetic field recreates the electric field an oscillating voltage applied to the antenna makes the charges in the antenna vibrate up and down sending out a synchronized pattern of electric and magnetic fields
