What is energy that travels across distance in the form of EM waves?
"EM" stands for "electromagnetic" waves, a broad description that includes radio, microwave, heat, light, gamma rays and cosmic rays.
What is an example of a wave that requires a medium to move through?
Sound wave.Any mechanical vibration requires a physical medium to travel through. All longitudinal, like earthquakes.Sound does not travel in space.A wave that travels through a vacuum is an Electromagnetic waves. ie it is a disturbance that propagates through space and time. EM waves vary in frequency producing light, infra-red, ultraviolet, radio waves etc...Sound waves are mechanical vibration through a medium, differing frequencies produce different pitches of sound.
How do EM waves travels?
Electromagnetic (EM) waves are self-propagating waves of electric and magnetic fields that travel through space at the speed of light. They do not require a medium to travel through, and can travel through a vacuum. EM waves are produced by the vibrations of charged particles and have both electric and magnetic components perpendicular to each other.
Is a EM wave a sound wave?
No, electromagnetic (EM) waves are different from sound waves. EM waves are vibrations of electric and magnetic fields that do not need a medium to travel through, while sound waves are mechanical vibrations that require a medium, such as air or water, to propagate.
What does E in EM wave stand for?
EM waves stand for Electromagnetic waves.
Type of radio waves that excites water molecules?
Radio waves are a form of electromagnetic radiation. The EM waves used in microwaves are chosen speciiffically for there ability to excite water molecules.
Why electromagnetic waves cannot be used in SONAR?
Electromagnetic waves cannot be used in SONAR because they do not travel well through water. Water absorbs and scatters electromagnetic waves, making them unsuitable for underwater communication and sensing. SONAR systems use sound waves, which can travel long distances in water and are better suited for detecting objects underwater.
What does the e stand for in EM waves?
EM waves stand for Electromagnetic waves.
How are EM waves formed?
When electrical charges get accelerated then it produces a kind of disturbance both electrical and magnetic in two perpendicular directions varying sinusoidally with time. The electrical vector and magnetic vector both will be perpendicular to the direction in which disturbance is propagating. Hence the electromagnetic wave is termed as transverse wave.
What is the passage of an EM wave through a medium?
when EM waves encounter a material medium, they can interact with it in much the same way that mechanical waves do. A mechanical wave transfer energy in two ways. As it travels, the wave moves potential energy from one place to another.
Which EM waves have the longest wavelenghts?
Radio waves
Are em waves longitudinal are transverse?
EM waves are both Transverse and Longitudinal.
