What is the Relationship Among Frequency Wavelength and Wave Speed

What is the Relationship Among Frequency Wavelength and Wave Speed.

What is Frequency?

Frequency is defined as the number of oscillations of a wave per unit time being, measured in hertz(Hz). The frequency is directly proportional to the pitch. Humans can hear sounds with frequencies ranging betwixt 20 – 20000 Hz. Sounds with frequencies over the human ears range are known equally ultrasound, and sounds with frequencies less than the audible range are known as infrasound.

Electromagnetic Radiation

You demand to know what Wavelength and frequency mean to sympathize their relationship.

What is Wavelength?

All points on a wave oscillate, i.eastward., all points on a wave exhibit a type of regular change in a particular value. For example, when y’all make a wave by wiggling upward and down, the rope molecules repeatedly motion upwardly and downwardly. When you consider an electromagnetic wave, the value of magnetic and electric fields keeps changing considering of the wave at a point. If the wave is not a short pulse, the value of electrical and magnetic fields proceed changing at any point. For example, two points on a moving ridge that attain their maximum value oscillate simultaneously.

Wavelength is defined as the altitude between ii most near points in phase with each other. Hence, two side by side peaks or troughs on a moving ridge are separated by a distance of a unmarried consummate wavelength. More often than not, we employ the letter of the alphabet lambda (λ) to describe the wavelength of a moving ridge.

Relation betwixt Frequency and Wavelength

Y’all tin create a wave having some frequency on a rope and and then gradually make it faster. During this, y’all will detect that every bit the wavelength becomes shorter. Therefore, the relation between frequency and wavelength does exist, so let’southward detect out what exactly this relationship is.

Another quantity is Menstruum (T) which can be used to describe a wave. It is defined as the fourth dimension taken to complete one oscillation. Considering frequency determines the number of times a wave oscillates and it tin be expressed as,
f = ane / t

Every point on the wave returns to the aforementioned value afterwards one period since a wave undergoes one oscillation during one period. This occurs because every oscillation session travels a wavelength distance from ane period to stop.

The wave speed (five) is defined as the distance travelled by a moving ridge per unit of fourth dimension. If considering that the wave travels a distance of one wavelength in one menstruation,

ν=λ/T

As we know that T = one/f, hence we tin can express the above equation equally,

V = f λ

The wave speed is equal to the product of its frequency and wavelength, and this implies the relationship between frequency and wavelength.
