Wave is the propagation of disturbance from one place to another in an organised manner. Waves can be mechanical waves or non-mechanical waves. Mechanical waves like sound waves, require a medium to propagate. While electromagnetic waves are non-mechanical waves that do not require a medium and can travel through a vacuum.
If the particles of the medium move in a direction perpendicular to the wave propagation then the waves are called transverse waves. Longitudinal waves are waves in which the particles of the medium vibrate parallel to the direction of wave propagation.
5 Important Properties of Waves
The main properties of waves are as follows –
Property 1:Amplitude
The maximum displacement of the wave from the mean position is called the amplitude of the wave. It is the maximum height from the centre line to the crest or the trough. The crest is the highest point of the wave and the trough is the lowest point of the wave. Amplitude is measured in metres.
Property 2: Frequency
The number of vibrations passing a fixed point in a given amount of time is called frequency. The unit of frequency is Hertz.
Property 3: Wavelength
Wavelength is the distance between two identical points (adjacent crests or troughs). It is measured in metres. Frequency and wavelength are inversely proportional to each other.
Property 4: Time Period
The time taken by a complete wave to pass through a particular point is called the time period. The time period is measured in seconds. The time period is the reciprocal of the frequency.
Property 5: Speed
For a wave, speed is the distance travelled by a particular point on the wave in the given interval of time. Speed is measured in metres per second.

Frequently Asked Questions on Properties of Waves
Q1
What are the main properties of waves?
The basic properties of a wave are wavelength, frequency, time period, speed and amplitude.
Q2
What is wave height?
The vertical distance between the crest and the trough is called the wave height.
Q3
What is the frequency of the wave?
The number of vibrations crossing a fixed point in the time given is called frequency.
Q4
What is the highest point of a wave called?
The highest point of the wave is called the crest.
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.
Slinky Wave Demonstration: A slinky toy can be an excellent tool to demonstrate wave properties such as wavelength, frequency, and amplitude. Longitudinal waves can be demonstrated by compressing and expanding the slinky, while transverse waves can be shown by moving the slinky up and down.
They include amplitude, frequency, period, wavelength, speed, and phase. Each of these properties is described in more detail below. When drawing a wave or looking at a wave on a graph, we draw the wave as a snapshot in time.
However, all waves have common properties-amplitude, wavelength, frequency, and speed. Amplitude describes how far the medium in a wave moves. Wavelength describes a wave's length, and frequency describes how often it occurs. Speed describes how quickly a wave moves.
Waves can be described by several properties that can be measured. The height of a wave and its speed are two such properties. Other important properties include amplitude, wavelength, cycle, frequency, and period.
A wave is a disturbance in a medium that carries energy without a net movement of particles. It may take the form of elastic deformation, a variation of pressure, electric or magnetic intensity, electric potential, or temperature.
The three terms used when describing a wave are: wavelength (the length of one wave), amplitude (the height of a wave from equilibrium position to peak) and frequency, (the number of waves that pass a point in one second).
The highest part of the wave is called the crest. The lowest part is called the trough. Wave height is the overall vertical change in height between crest and trough.

The basic properties of waves are measurable in units of distance and time. Two properties that can be measured directly are wavelength (L), which is the distance or length from wave crest to wave crest, and period (T), which is the time it takes a wave to pass a fixed point (Fig.
The basic properties of waves are measurable in units of distance and time. Two properties that can be measured directly are wavelength (L), which is the distance or length from wave crest to wave crest, and period (T), which is the time it takes a wave to pass a fixed point (Fig. 4.2).
When we graph waves, we are using a mathematical model to represent their properties. Representing a wave's position as a function of distance helps us find its wavelength. Representing a wave's position as a function of time can help us find its period and from there its frequency.
