# Is sound an electromagnetic wave?

20
Sound waves are examples of mechanicalwaves while light waves are examples ofelectromagnetic waves. Electromagnetic waves arecreated by the vibration of an electric charge. This vibrationcreates a wave which has both an electric and a magneticcomponent.

Considering this, why is sound an electromagnetic wave?

Electromagnetic radiation is the propagationthrough space of electrical and magnetic waves whilesound is the result of small changes in the air pressurethat propagate through the air. We can sometimes seeelectromagnetic radiation (as light) or feel it (as warmth)while we can only hear sound.

how are sound waves and electromagnetic waves similar? Sound waves are longitudinal waves thatis, are transmitted in the same direction of oscillation ofthe particles in the medium. Electromagnetic waves aretransverse ie, the electric and magnetic fields, which areperpendicular to each other, oscillate perpendicularly to thedirection of wave propagation.

Also know, is sound an EM wave if not what kind of wave is it?

No, sound is not an electromagneticwave. Sound is a longitudinal mechanical (pressure)wave, which requires a medium in which to travel. The mediumcan be a gas, a liquid, or a solid. EM waves do notneed a medium in which to travel.

How is electromagnetic wave produced?

An electromagnetic wave can be created byaccelerating charges; moving charges back and forth willproduce oscillating electric and magnetic fields, and thesetravel at the speed of light.

## How far can electromagnetic waves travel?

In a vacuum, EM waves travel at a constant speed,and they travel very fast—about 300,000 kilometers(186,000 mi) per second. In 1 second, an EM wave can travela distance greater than 7 times the distance aroundEarth.

## How do waves travel?

Sea waves travel as up-and-down vibrations: thewater moves up and down (without really moving anywhere) as theenergy in the wave travels forward. Waves like thisare called transverse waves. That just means the watervibrates at right angles to the direction in which the wavetravels.

## Is sound a longitudinal wave?

Sound waves in air (and any fluid medium) arelongitudinal waves because particles of the medium throughwhich the sound is transported vibrate parallel to thedirection that the sound wave moves.

## At what speed do electromagnetic waves travel in a vacuum?

In a vacuum, all electromagnetic wavestravel at approximately 3 x 10^8 m/s - the fastest speedpossible.

## What is the #1 difference between mechanical and electromagnetic waves?

Electromagnetic waves are waves that haveno medium to travel whereas mechanical waves need a mediumfor its transmission. Electromagnetic waves travel ina vacuum whereas mechanical waves do not. While anelectromagnetic wave is called just a disturbance, amechanical wave is considered a periodicdisturbance.

## What is the definition of an electromagnetic wave?

Definition of electromagnetic wave. : oneof the waves that are propagated by simultaneous periodicvariations of electric and magnetic field intensity and thatinclude radio waves, infrared, visible light, ultraviolet,X-rays, and gamma rays.

## Is red light an electromagnetic wave?

Red light has a wavelength of ~700 nm, and afrequency of ~4.3*1014 Hz. Visible light makes upjust a small part of the full electromagnetic spectrum.Electromagnetic waves with longer wavelengths and lowerfrequencies include infrared light, microwaves, and radioand television waves.

## How fast do waves travel?

So, for a surface gravity wave of length 10m, the packetwould travel at approximately 1.97 m/s, or 4.4 mph. Assuminga Pacific Ocean 5000 miles in width, it would take 1136.36 hours,or 47.34 days for a deep water wave to traverse the Pacificbasin.

## Is radio a sound wave?

What Are Radio Waves? A radio tunerreceives radio waves and converts them to mechanicalvibrations in the speaker to create sound waves that can beheard.

## Can sound waves travel through a vacuum?

They can also feel the waves. Soundcannot travel through a vacuum. A vacuum is an areawithout any air, like space. So sound cannot travelthrough space because there is no matter for the vibrations towork in.

## Why sound is not an electromagnetic wave?

(This is why sound waves are not typicallyconsidered part of the electromagnetic spectrum, sincesound requires a medium—such as air orwater—through which to propagate, whereas electromagneticwaves have little difficulty in radiating through the vacuum ofspace.)

## What are the types of waves?

There are three categories:
• Longitudinal wave *s - Movement of the particles areparallel to the motion of the energy.
• Transverse wave *s - movement of the particles areat right angles (perpendicular) to the motion of the energy.
• Surface wave *s - particles travel in a circularmotion.

## How fast do radio waves travel in space?

Actually, radio waves travel very quickly throughspace. Radio waves are a kind ofelectromagnetic radiation, and thus they move at thespeed of light. The speed of light is a little lessthan 300,000 km per second.

## What are the properties of electromagnetic waves?

These electric and magnetic waves travelperpendicular to each other and have certaincharacteristics, including amplitude, wavelength, andfrequency. General Properties of all electromagneticradiation: Electromagnetic radiation can travel throughempty space.

## What type of waves are electromagnetic waves?

This means that it is correct to talk about the energyof an X-ray or the wavelength of a microwave or the frequency of aradio wave. The electromagnetic spectrum includes,from longest wavelength to shortest: radio waves,microwaves, infrared, optical, ultraviolet, X-rays, andgamma-rays.

## Where do electromagnetic waves transfer energy?

In electromagnetic waves, energy istransferred through vibrations of electric and magneticfields. In sound waves, energy is transferredthrough vibration of air particles or particles of a solid throughwhich the sound travels. In water waves, energy istransferred through the vibration of the waterparticles.

## Is microwave an electromagnetic wave?

Microwave. Microwaves areelectromagnetic waves with wavelengths longer than those ofterahertz (THz) wavelengths, but relatively short for radiowaves. Microwaves have wavelengths approximately inthe range of 30 cm (frequency = 1 GHz) to 1 mm (300GHz).
