# What type of wave is light?

## What type of wave is light?

electromagnetic wave
1. Light as a wave: Light can be described (modeled) as an electromagnetic wave. In this model, a changing electric field creates a changing magnetic field. This changing magnetic field then creates a changing electric field and BOOM – you have light.

## Is light wave and sound wave the same?

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.

Is light a transverse wave?

transverse wave, motion in which all points on a wave oscillate along paths at right angles to the direction of the wave’s advance. Surface ripples on water, seismic S (secondary) waves, and electromagnetic (e.g., radio and light) waves are examples of transverse waves.

### What type of wave is sound wave?

longitudinal waves
Sound waves in air (and any fluid medium) are longitudinal waves because particles of the medium through which the sound is transported vibrate parallel to the direction that the sound wave moves. A vibrating string can create longitudinal waves as depicted in the animation below.

### How are sound waves similar to light waves?

Light and sound are both waves. The propagation, or distribution of sound, is actually very similar to light, just a whole lot slower. The waves of sound or light both reflect, refract, and attenuate depending on their environment.

How are light waves different from water and sound waves?

There are different types of waves. Sound waves travel through air and allow us to hear sound. Water waves move on top of water. Light waves move in straight lines through space.

#### Are light waves longitudinal waves?

Explanation: Sound is a longitudinal wave, while light is a transverse wave. Polarization requires the direction of the wave to be perpendicular to the direction of propogation; only light can do this. Doppler effect, refraction, and interference occur in both wave types.

#### What is the nature of sound wave in air?

Sound waves in air are longitudinal waves since particles of the medium through which the sound is shipped vibrate corresponding to the course that the sound wave moves.

What happens to the air particles when sound travels through air?

Solution: When sound travels through air, the air particles always vibrate in the same direction of wave propagation resulting in the transfer of energy.

## What is sound what type of waves are sound waves in air?

Sound waves in air (and any fluid medium) are longitudinal waves because particles of the medium through which the sound is transported vibrate parallel to the direction that the sound wave moves.

## What type of wave is sound 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 happens to sound waves when they travel through air?

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. If a sound wave is moving from left to right through air, then particles of air will be displaced both rightward and leftward as the energy of the sound wave passes through it.

### Is sound a pressure wave or a sound wave?

Sound is a Pressure Wave. 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.

### What is the mass of light and sound?

The “particles” of light are called photons and have no mass. In contrast, matter is made up of particles that do have mass. Sound is a little different in that it is the propagation of a pressure wave through a medium of particles.
