- A disturbance propagated from one place to another with no actual transport of matter.
- Without conveying a substance, all waves carry energy.
- As long as a wave has energy, it will continue to travel.
- Examples: sound waves, water waves, light waves, and stadium waves.
- Excitations of a (more or less) elastic medium produce waves.
- The wave is considered transverse if the disturbance occurs perpendicular to the wave's propagation direction.
- The disturbance is considered longitudinal if it occurs along the wave's propagation path.
- The medium vibrates to and fro at right angles to the wave/energy propagation direction in this sort of wave.
- In other words, a transverse wave occurs when the energy particles and wave particles form a perpendicular angle to each other.
- Radio waves, microwaves, ocean waves, wiggling thread, and polarisation waves are all examples of transverse waves.
- This is yet another significant wave deviation. The wave particles vibrate back and forth in the direction of wave/energy propagation.
- Between the wave particles and the energy particles, a zero-degree angle is generated. It can also be described as the displacement of the medium in the direction of the wave's movement.
- Sound waves and pressure waves are two examples of this sort of longitudinal wave.
Properties of waves
- A wave has a variety of features that define it. Amplitude, frequency, wavelength, velocity, and period are the qualities in question. Let's take a closer look at each of these elements one by one to gain a better understanding of them.
- Amplitude: A wave's amplitude is measured in meters. It refers to the amount of energy contained in the wave. The higher amplitude a wave has, the more strong and intense it is. The maximum displacement or total distance traveled by a wave in the medium is known as its amplitude.
- Wavelength: The distance between two successive troughs or crests of a wave is measured in wavelength. The length is expressed in meters. Lambda is the symbol for a wave's length, which is equal to the wave's velocity (in meters/sec) divided by the wavelength.
- Period of time: The overall time it takes for a wave to complete a single cycle is called the Time Period. It's counted in seconds. The letter 'T' is used to signify it. The frequency of a wave is the inverse of the time period.
- Velocity: Any wave's velocity is the rate at which it travels through one medium. It is expressed in meters per second. The product of wave frequency and wavelength, or the division of wavelength and period, yields velocity.
