# What are the basics of waves?

## What are the basics of waves?

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. All waves can be thought of as a disturbance that transfers energy.

## What are the formulas for waves?

To find the amplitude, wavelength, period, and frequency of a sinusoidal wave, write down the wave function in the form y(x,t)=Asin(kx−ωt+ϕ). The amplitude can be read straight from the equation and is equal to A. The period of the wave can be derived from the angular frequency (T=2πω).

What are waves 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.

What are four basic properties of waves?

No matter whether you are talking about vibrations or waves, all of them can be characterized by the following four characteristics: amplitude, wavelength, frequency, and speed.

### What are the five parts of a wave?

Vocabulary

• crest. Noun. the top of a wave.
• wave. Noun. moving swell on the surface of water.
• wave height. Noun. the distance between a wave’s trough and crest.
• wavelength. Noun. the distance between the crests of two waves.
• wave trough. Noun. the lowest part of a wave.

### What is the velocity of wave?

The velocity of a wave is equal to the product of its wavelength and frequency (number of vibrations per second) and is independent of its intensity.

Do waves move particles?

The particles do not move along with the wave; they simply oscillate up and down about their individual equilibrium positions as the wave passes by. Pick a single particle and watch its motion. The S waves (Secondary waves) in an earthquake are examples of Transverse waves.
