How do you calculate wave speed without the wavelength?

Answer 1

Well, isn't that just a happy little question? If you have the frequency of the wave and the medium it's traveling through, you can calculate wave speed using the formula speed = frequency x wavelength. If you don't have the wavelength, you might need to gather more information or use a different approach to determine the wave speed. Just remember, there are always different ways to approach a problem, and it's all part of the joy of learning!

Answer 2

Wave speed can be calculated using the formula: wave speed = frequency x wavelength. If you do not have the wavelength, you can still calculate the wave speed using the frequency and other known variables. For example, if you know the frequency and the period of the wave, you can use the formula: wave speed = frequency x period. Alternatively, if you know the wave speed and the frequency, you can rearrange the formula to solve for the wavelength: wavelength = wave speed / frequency.

Answer 3

Well, honey, you can't calculate wave speed without knowing the wavelength. It's like trying to bake a cake without flour - it's just not gonna work. So, if you want to find the wave speed, you better grab that wavelength and get crunching those numbers.

Answer 4

To calculate wave speed without the wavelength, you need either the frequency or the period of the wave. Use the formula speed = frequency x wavelength to find the speed if you have the frequency, or speed = wavelength / period if you have the period.

Answer 5

You can measure the wavelength without knowing the frequency. This is done by measuring the "nodes" between similar points of a single-frequency continuous wave. All you need is some simple lab equipment. http://www.ted.com/index.php/talks/view/id/237 [the guy measures the wavelength]

You can calculate the wavelength as follows: Wavelength times Frequency =Velocity (phase velocity in that medium) So the speed of sound in air is about 344 m/s. If the frequency is 1000 Hz, then the wavelength is 344/1000=.344 m. But in this simple relationship you can't call both wavelength and frequency unknowns. You have to have in hand one or the other. See: http://en.wikipedia.org/wiki/Wavelength

Answer 6

Wave length in water can be computed from wave period as follows: L = g x T x T/(2 x PI()) = 1.56 T^2 This is only for deep water waves (i.e. water depth greater than wave length), otherwise the wave length at a given water depth, in shallow water, can be determined using : L = g/(2*PI) * T^2 * tanh ((2*PI*h)/L) (where h is the water depth), which can also be exprimed as L = L0 * tanh ((2*PI*h)/L), where L0 is the deep water conditions wave length.

Answer 7

Wavelength lambda and frequency f are connected by the speed c of the medium.

c can be air = 343 m/s at 20 degrees Celsius (68 dgrees Fahrenheit) or

c can be water at 0 dgrees = 1450 m/s.

c can be light waves or

c can be electromagnetic waves = 299 792 458 m/s.

The formulas are:

c = lambda x f

f = c / lambda

lambda = c / f

Answer 8

You need some information to get the wave speed. You could measure the wave speed, or simply get it from observation for certain waves. In the relation speed = wavelength x frequency, if you have two pieces of information you can calculate the third. If you don't have the result from an observation, and you don't know neither the wave speed and the wavelength, then, quite simply, you don't have enough information.

Answer 9

You can't. The wavelength alone isn't enough information to tell you the frequency.

The three quantities that all go together are the frequency, wavelength, and speed.

Their relationship is: Wave speed = (wavelength) x (frequency) Knowing any two of them, you can calculate the third one.
