are electromagnetic waves light or sound
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. The Characteristics of Sound and Light Waves. There are many different kinds of waves. Waves can carry a little energy or a lot. They can be short or long. They can be rare or frequent. They can travel fast or slow. Sound waves, light waves, X-rays, microwaves, and ocean waves are but a few examples. All waves, however, share certain basic characteristics. The various properties of electromagnetic waves and sound waves are described below. Sound waves are mechanical waves generated from vibrations within a medium. Sound can exist as longitudinal mechanical waves, which are also known as compression waves. These waves can travel through solid, liquid, gas or plasma media. Sound waves require a medium to travel. Mechanical waves, unlike electromagnetic waves, require the presence of a material medium in order to transport their energy from one location to another. Sound waves are examples of mechanical waves while light waves are examples of electromagnetic waves. Electromagnetic waves are created by the vibration of an electric charge. This vibration creates a wave which has both an electric and a magnetic component. An electromagnetic wave transports its energy through a vacuum at a speed of 3.00 x 108 m/s (a speed value commonly represented by the symbol c). The propagation of an electromagnetic wave through a material medium occurs at a net speed which is less than 3.00 x 108 m/s. This is depicted in the animation below. The mechanism of energy transport through a medium involves the absorption and reemission of the wave energy by the atoms of the material. The various properties of electromagnetic waves and sound waves are described below. Sound Waves: Sound waves are mechanical waves generated from vibrations within a medium. Sound can exist as longitudinal mechanical waves, which are also known as compression waves. These waves can travel through solid, liquid, gas or plasma media. Sound waves require a medium to travel. 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. Electromagnetic Waves Light, radio waves, and X rays are. examples of electromagnetic waves. Just like waves on a rope, electromagnetic waves are transverse waves. However, electro-. magnetic waves contain electric and magnetic parts that vibrate. up and down perpendicular to the direction the wave travels. Main Idea Light waves are. electromagnetic waves that. travel in matter or space. Ups and Downs. This wind surfer is riding high for now, but that will change soon. The energy carried by ocean waves makes this a thrilling ride, but. other waves carry energy, too. Sound waves and light waves carry. energy that enable you to hear and see the world around you. Science Journal Write a short paragraph describing water waves you have seen. Sound waves require a material medium for propagation, while propagation of electromagnetic waves do not require a medium. In other words, electromagnetic waves are able to travel through a vacuum, but sound waves, being mechanical waves, cannot travel through a vacuum. There is no sound in space because there are no molecules there to transmit the sound waves. Electromagnetic waves are different from sound waves because they do not need molecules to travel. This means that electromagnetic waves can travel through air and solid materials - but they can also travel through empty space.
It is a light wave.
