Wavelength Calculator

Results

Wavelength calculator is designed to assist you in calculating the wavelength of light in different mediums. By using wavelength calculator, you can calculate the wavelength of light in vacuum, air, or water.

What is Wavelength?

Wavelength is defined as the horizontal distance between two crests or troughs of a wave. Whereas a wave can be marked as a mode of transmission that carries energy without the uptake of the matter.

In other words, a wave is something that travels through a medium to carry energy from one place to another. Such as light or sound travels in the air.

Wavelength formula

The wavelength of any wave can be represented using the Greek letter called lambda (λ). Whereas λ is the wavelength, v is the velocity (speed of the wave) and f is the frequency of the wave.

The wavelength formula is written as

$$\lambda=\frac{v}{f}$$

Wavelength Units

The SI unit of measuring wavelength is meter (m) so we measure the unit of length in meter (m). The wavelength can also be measured in nanometers or angstrom. The wavelength of visible light ranges from 400 to 700 nanometres (nm).

How to find Wavelength?

Having the value of the wavelength of a traveling object, we can describe a wave in a better wave. This is so because the wavelength is referred to as a property of a wave that can be used to describe a wave. Simply, a wavelength determines the complete cycle of a wave.

Basic Properties of a Wave

There are five basic properties of a wave. These are:

  • Amplitude
  • Wavelength
  • Frequency
  • Period
  • Velocity

All of these properties of a wave can be used to describe it properly.

Relation Between Frequency and Wavelength

The relation between the frequency and the wavelength of a wave can be marked by the inverse proportion. In simple words, the length of a wave is inversely proportional to its frequency.

It means that the higher the frequency, the shorter the wavelength and the lower the frequency, the longer the wavelength.

Does the Wavelength of Light varies with the medium in which it travels?

The wavelength of traveling object varies with respect to the medium it travels in. Likewise, the wavelength of the light varies with respect to the medium in which it travels.

How to Calculate Wavelength of a Wave?

The wavelength of a wave can be calculated by using the wavelength formula. Wavelength formula is λ = v / f.

For calculating wavelength, first we need to determine the values of velocity and frequency of the wave. Another aspect to keep in mind is the medium in which the wave travels.

Example

Suppose that the light is traveling through the vacuum and you have to measure its wavelength.

You are required to determine the value of v and f of light to calculate λ of the light traveling through the vacuum.

v= 299,792,458 m/s

f= 439 hertz

By putting the values of f and v in the wavelength formula, we will get:

λ= 299,792,458/439 = 682899 m

Precisely, you just have to divide the velocity of the energy by the frequency of the energy to determine the value of its wavelength.

What is Wavelength Calculator?

Although we can calculate wavelength manually using above-mentioned process but wavelength calculator can assist you a lot in finding wavelength & frequency.

CALCULATORED provides this wavelength calculator to find the wavelength of light in different vacuums. This wavelength finder is super accurate and free to use.

How to Use Wavelength Calculator?

To determine the wavelength of light you are required to input the value of the frequency of the light after selecting the medium of light.

To use this calculator follow these simple steps:

STEP #1: Select the medium in which the light is traveling (Vacuum, Air, Water).

STEP #2: Enter the value of the Frequency.

STEP #3: Select respective unit (Hz, KHz, MHz, GHz).

STEP #4: Click on "Calculate" button.

Once you clicked on the calculate button, the wavelength calculator will instantly show you the accurate result.
