# What are 3 differences between sound waves and electromagnetic waves?

Contents

Sound creates pressure variations (waves) in matter, such as air or water, or your eardrum. Conversely, radio waves are electromagnetic waves, like visible light, infrared, ultraviolet, X-rays, and gamma rays. EM waves don’t need a medium in which to propagate; they can travel through a vacuum, such as outer space.

## What are the differences between sound waves and electromagnetic waves?

Propogation: Sound waves are longitudinal, meaning that the vibrations occur parallel to the direction of propogation (travel). Electromagnetic waves are transverse, meaning that the vibrations occur perpendicular to the direction of propogation.

## What are 3 differences between light and sound waves?

Light waves are electromagnetic waves while sound waves are mechanical waves. Light waves are transverse while sound waves are longitudinal. Light waves can travel in vacuum. Sound waves require a material medium to travel, and hence, cannot travel in vacuum.

## What is the major 3 differences between mechanical waves and electromagnetic waves?

A mechanical wave can be of three types, longitudinal, transverse, and surface waves whereas an electromagnetic wave can only be a transverse wave. An example of a mechanical wave is ripples in a water body whereas those of an electromagnetic wave are microwaves, radio waves, and ultraviolet rays.

## What are 3 characteristics of electromagnetic waves?

Electromagnetic waves are typically described by any of the following three physical properties: frequency (f), wavelength (λ), or intensity (I). Light quanta are typically described by frequency (f), wavelength (λ), or photon energy (E). The spectrum can be ordered according to frequency or wavelength.

## What is the difference between sound waves and water waves answer?

Water waves shake energy over the surface of the sea, while sound waves thump energy through the body of the air. Sound waves are compression waves. They’re also called longitudinal waves because the air vibrates along the same direction as the wave travels.

## How are electromagnetic waves different from sound and water waves?

Like ocean waves, sound waves need a medium to travel through. … Electromagnetic waves are unlike 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.

## What is the difference between sound and sound waves?

Sound waves

Anything that vibrates is producing sound; sound is simply a longitudinal wave passing through a medium via the vibration of particles in the medium. Consider a sound wave traveling in air.

## What are the differences between light waves and sound waves quizlet?

Light waves DO NOT require a medium, they travel fastest in empty space; Sound waves REQUIRE a medium, they travel fastest in dense material like solids. Sound is a longitudinal wave. Define and give an example of reflection for a light wave and a sound wave. … Light does not require a medium through which to travel.

## What are differences between light and sound?

– Sound is only a wave, whereas light exhibits both wave and particle properties. – Sound is a longitudinal wave, but light is a transverse wave. – Sound needs a material medium to travel, light can propagate through vacuum also. – Light travels much faster than the sound.

## What are 3 examples of electromagnetic waves?

Radio waves, microwaves, visible light, and x rays are all examples of electromagnetic waves that differ from each other in wavelength.

## Are sound waves electromagnetic waves?

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. … The mechanism of energy transport through a medium involves the absorption and reemission of the wave energy by the atoms of the material.

## What is sound in waves?

Sound is a mechanical wave that results from the back and forth vibration of the particles of the medium through which the sound wave is moving. … The motion of the particles is parallel (and anti-parallel) to the direction of the energy transport. This is what characterizes sound waves in air as longitudinal waves.

## What are the 4 main properties of electromagnetic waves?

Every form of electromagnetic radiation, including visible light, oscillates in a periodic fashion with peaks and valleys, and displaying a characteristic amplitude, wavelength, and frequency that defines the direction, energy, and intensity of the radiation.

## What are two properties of electromagnetic waves?

Like other waves, electromagnetic waves have properties of speed, wavelength, and frequency.

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

Electromagnetic waves differ from mechanical waves in that they do not require a medium to propagate. This means that electromagnetic waves can travel not only through air and solid materials, but also through the vacuum of space.
