# What are the characteristics of a wave motion?

CHARACTERISTICS OF WAVE MOTION. The two types of wave motion, transverse and longitudinal, have many of the same characteristics, such as frequency, amplitude, and wavelength. Another important characteristic that these two types of wave motion share is VELOCITY.

Then, what are two types of wave motion?

Mechanical Waves are waves which propagate through a material medium (solid, liquid, or gas) at a wave speed which depends on the elastic and inertial properties of that medium. There are two basic types of wave motion for mechanical waves: longitudinal waves and transverse waves.

What are waves and sound?

In physics, sound is a vibration that typically propagates as an audible wave of pressure, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain.

What causes wave motion?

Types of wave motion. Two types of waves exist: transverse and longitudinal. A transverse wave is one that causes the particles of the surrounding medium to vibrate in a direction at right angles to the direction of the wave. A water wave is an example of a transverse wave.

## What are the four characteristics of a wave?

The main properties of waves are defined below.

• Amplitude: the height of the wave, measured in meters.
• Wavelength: the distance between adjacent crests, measured in meters.
• Period: the time it takes for one complete wave to pass a given point, measured in seconds.
• ## What are some examples of an electromagnetic wave?

Examples of Electromagnetic Waves. Radio waves, Light waves, thermal radiation, X ray, visible light, microwave, infrared, gamma rays etc. are the example of electromagnetic waves. These waves together form the electromagnetic spectrum.

## What are the different types of waves?

There are three categories:

• Longitudinal wave *s – Movement of the particles are parallel to the motion of the energy.
• Transverse wave *s – movement of the particles are at right angles (perpendicular) to the motion of the energy.
• Surface wave *s – particles travel in a circular motion.
• ## What is the very top of a wave called?

As is shown on the figure, wave height is defined as the height of the wave from the wave top, called the wave crest to the bottom of the wave, called the wave trough. The wave length is defined as the horizontal distance between two successive crests or troughs.

## What is the difference between a compression and a rarefaction?

9.2 Compression and rarefaction (ESACT) However instead of crests and troughs, longitudinal waves have compressions and rarefactions. A compression is a region in a longitudinal wave where the particles are closest together. A rarefaction is a region in a longitudinal wave where the particles are furthest apart.

## What is the wavefront of a wave?

In physics, a wavefront is the locus of points characterized by propagation of positions of identical phase: propagation of a point in 1D, a curve in 2D or a surface in 3D. For an electromagnetic wave, the wavefront is represented as a surface of identical phase, and can be modified with conventional optics.

## Why are waves important in science?

As sound waves propagate through a medium, the molecules collide with each other in the same direction as the sound is moving. Waves in the ocean are mostly generated by the wind moving across the ocean surface. One of the most important things to remember about waves is that they transport energy, not matter.

## What is a wave in physics?

Waves involve the transport of energy without the transport of matter. In conclusion, a wave can be described as a disturbance that travels through a medium, transporting energy from one location (its source) to another location without transporting matter.

## How would you describe the motion of a transverse wave?

Transverse waves are always characterized by particle motion being perpendicular to wave motion. A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves.

## What is meant by a progressive wave?

Progressive Waves. Waves move energy from one place to another. In a progressive wave the wave front moves through the medium. Transverse waves are waves where the displacement of the particles in the medium is perpendicular to the direction the wave is travelling in.

## What do you mean by wave motion?

Wave motion, propagation of disturbances—that is, deviations from a state of rest or equilibrium—from place to place in a regular and organized way. Most familiar are surface waves on water, but both sound and light travel as wavelike disturbances, and the motion of all subatomic particles exhibits wavelike properties.

## What causes wave motion?

Types of wave motion. Two types of waves exist: transverse and longitudinal. A transverse wave is one that causes the particles of the surrounding medium to vibrate in a direction at right angles to the direction of the wave. A water wave is an example of a transverse wave.

## How is energy transferred by a wave?

Waves can transfer energy over distance without moving matter the entire distance. For example, an ocean wave can travel many kilometers without the water itself moving many kilometers. The water moves up and down—a motion known as a disturbance. It is the disturbance that travels in a wave, transferring energy.

## What is the definition of mechanical wave?

A mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium. While waves can move over long distances, the movement of the medium of transmission—the material—is limited. Therefore, the oscillating material does not move far from its initial equilibrium position.

## What is a sound wave caused by?

Sound is produced when something vibrates. The vibrating body causes the medium (water, air, etc.) around it to vibrate. Vibrations in air are called traveling longitudinal waves, which we can hear. Sound waves consist of areas of high and low pressure called compressions and rarefactions, respectively.

## How do you measure and describe waves?

Sure! We’ve got a measure of distance from the wavelength of the wave, and we’ve got a measure of time from the frequency. You’ve learned five ways of describing a wave using your wave parameters. The period, frequency, amplitude, speed, and wavelength are used to distinguish and categorize waves into groups.

## What is the sound of a wave?

A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water, or any other liquid or solid matter) as it propagates away from the source of the sound. The source is some object that causes a vibration, such as a ringing telephone, or a person’s vocal chords.

## What are sound waves called?

Longitudinal and transverse waves. Sound is transmitted through gases, plasma, and liquids as longitudinal waves, also called compression waves. It requires a medium to propagate. Through solids, however, it can be transmitted as both longitudinal waves and transverse waves.

## What is an example of a sound wave?

Examples of Sound Energy. Sound energy is produced when an object vibrates. The sound vibrations cause waves of pressure that travel through a medium, such as air, water, wood or metal. Sound energy is a form of mechanical energy.
