Is an electromagnetic wave a sound wave? An electromagnetic (EM) wave is not a sound wave. A sound wave is mechanical energy, and an electromagnetic wave is electromagnetic energy. The EM wave could be a radio or light wave, but in any case, it is composed of moving electric and magnetic fields. This electromagnetic wave can move through air or the vacuum of space, but sound (or any mechanical wave) must have a medium to travel through.

Properties of Light There are some general properties shared by all forms of electromagnetic radiation: It can travel through empty space. Other types of waves need some sort of medium to move through: water waves need liquid water and sound waves need some gas, liquid, or solid material to be heard.

Electromagnetic radiation Classically, electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric and magnetic fields that propagate at the speed of light through a vacuum.lectromagnetic waves are produced whenever charged particles are accelerated, and these waves can subsequently interact with any charged particles. EM waves carry energy, momentum and angular momentum away from their source particle and can impart those quantities to matter with which they interact.

Temperature System Electromagnetic radiation is a form of energy. The light that we see is a type of electromagnetic radiation. However it is only a very small part of the entire electromagnetic spectrum. Sound, another form of energy, is not part of this spectrum.Electromagnetic radiation is different from sound in that it can travel in space and does not need a medium like air or water to travel through. Electromagnetic radiation is made when an atom absorbs energy.The absorbed energy causes one or more electrons to change their locale within the atom. When the electron returns to its original position, an electromagnetic wave is produced.lectromagnetic radiation is a form of energy. The light that we see is a type of electromagnetic radiation. However it is only a very small part of the entire electromagnetic spectrum. Sound, another form of energy, is not part of this spectrum.

Are electromagnetic waves transverse or longitudinal waves? light waves or electromagnetic waves are transverse and sound waves are longitudinal. Electromagnetic waves can be both transverse and longitudinal waves. Transverse waves are like ocean waves. They move the medium perpendicular to the medium which is the substance the wave is traveling on.

- Both the waves in the flag and the ocean waves are waves that you can see. There are other kinds of waves. We cannot see these waves, but we experience them every day. These waves are called electromagnetic waves. Sound is also a type of wave that we cannot see. Like ocean waves, sound waves something to travel through like waves through the ocean or through a flag. Sound can travel through air because air is made of molecules. These molecules carry the sound waves by bumping into each other, like dominoes knocking each other over.

Electromagnetic radiation Visible light is electromagnetic radiation, as is invisible light, such as radio, infrared, and X-rays. Classically, electromagnetic radiation consists of electromagnetic waves, which are synchronized oscillations of electric and magnetic fields that propagate at the speed of light through a vacuum.

What is the primary difference between a mechanical wave and an electromagnetic wave? Report Abuse. Here's a few differences: Electromagnetic waves travel at the speed of light, mechanical waves travel at or below the speed of sound in the medium through which they're traveling. Mechanical waves can only flow through matter, EM waves can travel through free space (and through matter, as well).

Chapter 5 Light & Matter We say that light is an electromagnetic wave because light is a vibration of electric and magnetic fields. Because all electromagnetic waves travel at the speed of light, the product of their frequencies and wavelengths is always the speed of light.

Why Does Light Travel Faster Than Sound? Light travels faster than sound because sound waves can only travel as waves of pressure in a medium, whereas electromagnetic waves, of which light is made, move on their own even through vacuum.

What is Melancholy? However, if the state of melancholy goes on for too long it can worsen into clinical depression. Melancholy should pass with time. It is important to recognize when melancholy is inhibiting your life rather than playing a role in your ability to move forward.

- Light has both wave and particle properties. This is also the case for all matter. Electromagnetic radiation can be considered to consist of particle-like packets of wave-energy called photons. These massless particles travel at the speed of light (300,000 kilometers per second in a vacuum).

Light Nature of Light. Light is a wave, but the traveling disturbance is and electric and magnetic field, not a pressure variation like a sound wave. Sound has to travel through matter, but light does not have to travel through a medium. Therefore light can travel through a vacuum. Light waves also carry energy with them; that is how sunlight warms us up when we absorb it. In a vacuum, light travels with a speed of about 3´108 m/s, or 300,000,000m/s, i.e. very fast.

- Electromagnetic waves can be described by their wavelengths, energy, and frequency. All three of these things describe a different property of light, yet they are related to each other mathematically.This means that it is correct to talk about the energy of an X-ray or the wavelength of a microwave or the frequency of a radio wave.In fact, X-rays and gamma-rays are usually described in terms of energy, optical and infrared light in terms of wavelength, and radio in terms of frequency.n fact, X-rays and gamma-rays are usually described in terms of energy, optical and infrared light in terms of wavelength, and radio in terms of frequency.

- Electromagnetic Energy. Electromagnetic energy is an invisible form of energy in the transverse wave form. Of the many types of energy in our universe, this form of energy is the only one that does not require a medium or matter to travel on or in. This form of energy can travel through empty space as a transverse wave.

Electromagnetic Waves Light, microwaves, x-rays, and TV and radio transmissions are all kinds of electromagnetic waves. Different waves are made by their wavelengths. Electric fields are created by differences in voltage, the higher the voltage, the stronger will be the resultant field.lectromagnetic fields are found everywhere in nature, but are invisible to the human eye. There are also many human-made electromagnetic fields. An example of a human-made electromagnetic wave are X-Rays. There are many other types of waves that you can see on this website.

Electromagnetism Examples of electromagnetic waves traveling through space independent of matter are radio and television waves, microwaves, infrared rays, visible light, ultraviolet light, X-rays, and gamma rays. All of these waves travel at the same speed—namely, the velocity of light (roughly 300,000 kilometres, or 186,000 miles, per second).
