# Wave Formula

## Wave Formula

An energy transfer through a medium is referred to as a wave. The parachutes often create fantastic ripples that behave very much like waves. The wind provides energy to the ocean waves. This energy is absorbed by the water, which then radiates it as a wave. This wave can undoubtedly travel a great distance. Waves are best understood as swells and depressions. Additionally, waves are not only found in water. The powering of the waves can happen in a variety of ways, including the movement of the Earth’s plates or the creation of sound.

### What is Wave

A wave is a field disturbance where an oscillation of a physical property occurs repeatedly at each point. Additionally, a physical characteristic appears to move through space when it is part of a wave. Furthermore, electromagnetic and mechanical waves are frequent in the study of physics. The gravitational wave, physical wave, and plane wave are some additional types of waves.

### Wave Formula

The first particle of a periodic nature is disturbed by a vibrating source, which causes the production waves. This undoubtedly generates a wave pattern that starts to propagate through the medium and from particle to particle. Additionally, the frequency at which a particle vibrates is the same as the frequency of sound vibration.

Furthermore, the period of vibration of each individual particle is the same as the period of vibration of the source. Most importantly, one full wave cycle describes the full back and forth motion.

The movement of the wave is one wavelength in one period of time. Therefore, this data must be combined with the speed equation. As a result, one can assert that a wave’s speed is unquestionably its wavelength or period.

Wavelength/Period = Speed

The reciprocal of the frequency is also referred to as the period. In the equation above, the term “period” can be replaced with the expression “1/f”. As a result, the equation is rearranged to produce a new equation of the following form:

Wavelength x Frequency equals speed.

The waves equation is the formula or equation mentioned above. It explains the mathematical connection between a wave’s speed, wavelength, and frequency. Consequently, the formula or equation can be rewritten asThe waves equation is the formula or equation mentioned above. It explains the mathematical connection between a wave’s speed, wavelength, and frequency. Consequently, the formula or equation can be rewritten as:

v = f × λ

where, v = speed of

f = frequency

λ = wavelength

### Wave Formula Derivation

Obviously, the way the wave equation is derived depends on the situation. The derivation takes place in a specific straightforward physical environment. Additionally, this setting is that of Hooke’s law-compliant minor oscillations on a piece of string.

The forces acting on a tiny element of a certain mass dm contained in a tiny interval dx must be taken into account. When there is only a slight displacement, the horizontal force is close to zero.

### Solved Examples on Wave Formula

Q1. A wave has a frequency of 50 Hz. It also has a wavelength of 10 m. Find out the speed of the wave?

A1. We have:

f = 50 Hz

λ =10 m

v = ?

v = λ× f = (10 m)× (50 Hz) = 500 m/s

Therefore, speed of the wave is 500 m/s.
