# What do sound waves and electromagnetic waves have in common?

Contents

Both kinds of waves carry energy from one place to another and have a wavelength, frequency and velocity. The velocity of sound waves is much lower than that of electromagnetic waves.

## How are sound waves and electromagnetic waves similar?

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.

## What do sound and light waves have in common?

Sound and light are similar in that both are forms of energy that travel in waves. They both have properties of wavelength, freqency and amplitude. Here are some differences: Sound can only travel through a medium (substance) while light can travel through empty space.

## What do electromagnetic waves have in common?

They all have things in common. In a vacuum, they all travel at the same speed – the speed of light – which is 3 × 108 m/s. They are all transverse waves, with the oscillations being electric and magnetic fields. Like all waves, they can be reflected, refracted and diffracted.

## What do all sound waves have in common?

All kinds of waves have the same fundamental properties of reflection, refraction, diffraction and interference, and all waves have a wavelength, frequency, speed and amplitude. A wave can be described by its length, height (amplitude) and frequency. All waves can be thought of as a disturbance that transfers energy.2 мая 2011 г.

## Why electromagnetic wave can travel in vacuum?

An EM wave can travel without a material medium—that is, in a vacuum or space empty of matter—and does not lose energy as it moves. In theory, an EM wave can travel forever. Because they do not need a medium, EM waves can pass through outer space, which is a near vacuum.

## Are Sound Waves radio waves?

However, sound and radio waves are completely different phenomena. 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.

## Which is faster light or sound?

Light doesn’t need a medium to travel. The speed of sound through air is about 340 meters per second. It’s faster through water, and it’s even faster through steel. Light will travel through a vacuum at 300 million meters per second.

## Are light waves and sound waves the same?

Light waves are electromagnetic waves while sound waves are mechanical waves. Light waves are transverse while sound waves are longitudinal. … Sound waves require a material medium to travel, and hence, cannot travel in vacuum. The speed of light in a medium is constant.

## What are three similarities between light and sound waves?

Similarities

• light waves and sound waves can both be diffracted, reflected & refracted.
• they can both have a range of frequencies and wavelengths.
• they both transfer energy without transferring matter.

## Do all electromagnetic waves have the same energy?

Radio, microwaves, UV, visible light and gamma rays have completely different effects, but they’re all exactly the same kind of thing: electromagnetic radiation (EMR). They’re just waves of energy travelling through space — or through things. … Radio waves have got the lowest energy on the electromagnetic spectrum.

Gamma rays

## What electromagnetic waves can our eyes detect?

Visible light is the light that we can see, and thus is the only light detectable by the human eye. White light is visible light, and it contains all the colors of the rainbow, from red to violet. The range of visible wavelengths is 400 to 700 nanometers.

## How do waves behave?

Light waves across the electromagnetic spectrum behave in similar ways. When a light wave encounters an object, they are either transmitted, reflected, absorbed, refracted, polarized, diffracted, or scattered depending on the composition of the object and the wavelength of the light.

## What are sound waves created by?

Sound is produced when an object vibrates, creating a pressure wave. This pressure wave causes particles in the surrounding medium (air, water, or solid) to have vibrational motion. As the particles vibrate, they move nearby particles, transmitting the sound further through the medium.

## What can sound not travel through?

We know light can travel through a vacuum because sunlight has to race through the vacuum of space to reach us on Earth. Sound, however, cannot travel through a vacuum: it always has to have something to travel through (known as a medium), such as air, water, glass, or metal.21 мая 2020 г.
