speed of a wave

If you don’t know about the speed of a wave? Then don’t stress your brain, just continue reading this article, and you will get answers to all your questions regarding the wave. Wavelength is a topic in physics, and it is an important topic. Therefore, while learning it many are concerned about how to find the speed of a wave. So, to clear these concerns, here we will give you a direct formula to calculate the wave speed. Also, you can buy a wave speed calculator, if you don’t want to do many complex calculations, it’s all up to you. Let’s have a look at the speed of a wave

What Is The Speed Of A Wave? 

The speed of a wave is the distance travelled by a given point on the wave in a given interval of time. 

The speed of waves is determined by four factors and they are frequency, medium, wavelength, and temperature. To make it simple, they have calculated the speed of waves in some specific mediums which are constant. For instance, the speed of wave in water is 2 m/s, which is already calculated by professionals. So, you can direct put this value while solving problems related to wave speed in the water medium.

Calculate The Speed Of A Wave?

Let’s see how to find speed of a wave, 

Speed of wave =  Distance Time m/s 

You can also write this formula in its symbolic form as, 

V = D T m/s 

Here, T is a time period of wave in second 

          D is distance travelled by a wave in metre, and 

          m/s is a wave speed unit  

For example, if the given values are, D = 10 m, T = 1 s, then the speed of a wave is as, 

   Speed of wave = 10 1  = 10m/s 

As we all know, Time T is the inversion of frequency, so, from this formula you can say that the speed of V of a wave depends on its frequency f. From the above formula you can also write the frequency of a wave formula as, 

F = v 𝛌 Hz 

Since v = 𝛌 f,

Now, from these equations, you can answer what does the speed of a wave depend on from the above given two equations to determine the speed of a wave. Let’s know more about a wave. 

About A Wave 

So, a wave is a disturbance that moves along a medium like water, air, solid, etc, from one end to the other. For example, in an ocean wave moving along the medium water, you can observe that the crest of the wave is moving from one location to another over a given interval of time. When we talk about a wave, then we can’t forget the amplitude of a wave. So, wave amplitude is the distance from the center line to the top of a crest or to the bottom of a trough.  

A fact about a wave is that waves are involved in the transport of energy without the transfer of matter. So, a wave also is described as a disturbance that travels through a medium, transporting energy from one location to another without transporting matter. So, there will be no loss or consumption of medium.

What Does Speed Of Wave Depends On?

The speed of a wave is dependant on four factors: wavelength, frequency, medium, and temperature. Wave speed is calculated by multiplying the wavelength times the frequency (speed = l * f).

What Is Speed Of A Wave?

Wave speed is the speed at which a wave travels. Wave speed is related to wavelength, frequency, and period by the equation wave speed = frequency x wavelength. The most commonly used wave speed is the speed of visible light, an electromagnetic wave.

What Causes Wave Speed?

For example, waves on a string travel faster if you increase the tension of the string. Sound waves travel faster if you increase the temperature of the air. Changing the frequency or amplitude of the waves will not change the wave speed, since those are not changes to the properties of the medium.

Why Can’t You Change The Speed Of This Wave?

The speed of a wave is only altered by alterations in the properties of the medium through which it travels. The wavelength of a wave does not affect the speed at which the wave travels. The speed of a wave is only altered by alterations in the properties of the medium through which it travels.

How Do You Find Wave Speed Without Wavelength?

Using the leading edge measurements, one would calculate the velocity as the distance between the two set points divided by the time that elapses between the detection of the wave edge at each point.


From this article, you will be able to find the wave speed by using the direct formula. You can also find the wave speed by using the frequency-based formula, which is given above. Above, we have given an example of an ocean wave, but there are so many types of waves like sound waves, electronic waves, etc. Now, you may be thinking like how to find the speed of these other waves. So, the wave speed formula is the same for all types of waves. In fact, the wave is a constant only medium change. Now, without the speed of a wave calculator, you can easily calculate the speed of a wave
