First here is the equation
f=v/λ
It says that frequency is equal to the velocity divided by wavelength.
A good way to remember this equation is to imagine sound traveling for 1 second. In that one second, in air, it will travel 343 meters because the speed of sound is 343 m/s. Now the above equation divides the velocity of the wave by the wavelength of the wave. So imagine those 343 meters divided up into wavelengths. The number of wavelengths in those 343 meters is equal to the frequency.
The reason this is so is because the frequency of a wave is the number of cycles a specific point in the air will experience in one second as the wave passes by.
Now in one second 343 meters of that wave will pass by and we just calculated using v/λ how many cycles would be in those 343 meters.
So by thinking about it you can kind of understand why f=v/λ.
You can find the other related equations, v=fλ and λ=v/f, by rearranging that equation.
Another important related equation is this one.
f=1/T
or the frequency is equal to the inverse of the period.
To understand why this is the case, imagine a cork floating on the water as a wave goes by. The number of times the cork bobs up and down in one second is the frequency. If we knew the time it took the cork to bob up and down only once and then divide 1 second by that time, we would then have the number of times it bobs up and down in one complete second, which is the frequency.
Rearranging that equation you get T=1/f

The wave equation says that a wave's is equal to its wavelength times its frequency?
A wave equation is an equation that repeats y-values infinately creating a wave like pattern, a good example is the sine wave: http://en.wikipedia.org/wiki/Sine_wave
How are the frequency and the wavelength of a light wave related?
(Wavelength) x (frequency) = (wave speed) Wavelength = (speed) / (frequency) Frequency = (speed) / (wavelength) Note: This is true for any traveling wave, not only electromagnetic ones.
How is wavelength measure?
A wavelength is a measure of the distance between two consecutive peaks (or troughs) of a wave. For electromagnetic radiation, the wavelengths range from 10^-11 to 10^3 metres - a factor of 100 trillion. There is, therefore, no single instrument which can be used to measure across such a range.
If Two waves are traveling in the same medium with a speed of 340ms What is the difference in frequency of the waves if the one has a wavelength fo 5m and the other has a wavelength of 0.2m?
For a wavelengt lambda in air with the speed of sound of c = 340 meters per second the frequency f: f = c / lambda. A wavelength of 5 meters equals a frequency of 68 Hz. A wavelength of 0.2 meters equals a frequency of 1700 Hz. There is a useful calculator for converting wavelength to frequency and vice versa. Scroll down to related links and look at "Acoustic waves or sound waves in air".
What makes up a wavelength in a compressional wave?
In air,as you move along the wave the molecules go through a cycle where in one region they are closer together and then farther down there is another region where they are further apart. This cycle repeats. The Length of one of these cycles is the wavelength. Go to the Related Links below for good animations.
Why you do velocity analysis?
velocity analysis is done to check the velocity of different links moving with respect to different links.

What is the relationship between frequency speed and wavelength?
Speed of sound c is frequncy f times wavelength lambda. c = f times lambda Scroll down to related links and look at "Conversion: frequency f to wavelength lambda and wavelength to frequency".
How do you write a program to find the kinetic energy in C?
The equation to find kinetic energy is based on knowing the mass and velocity of the object in question. Specifically, the equation is as follows:KE = ½ mv2In C, this equation can be specified as:v*v*m/2...since it's half of the mass multiplied by the square of the velocity.If you haven't written a C program before, see the related links for a solid C tutorial, or try a Web search for c tutorial. Also included in the related links are pages about kinetic energy formulae.
What is equation governing kinematic links and pairs?
L=2p-4L= no. of linksp= no. of pairs
What is the equation that links the distance and speed and time of an object?
Distance = (speed) multiplied by (time)
What is the wavelength of radiation at a frequency of 543.3Hz?
For a frequency f in air with the speed of sound of c = 343 meters per second the wavelength lambda = c / f. A frequency of 543.3 Hz meters equals a wavelength of 0.6313 meters. There is a useful calculator for converting wavelength to frequency and vice versa. Scroll down to related links and look at "Acoustic waves or sound waves in air".

What is C in in the equation of atom bomb?
'c' in the equation E=mc2 represents the speed of light (in a vacuum).For more information, see Related links below.
Discuss effect of temperature on the velocity of sound?
Scroll down to related links and look at "Speed of sound - Wikipedia". There is a table of the effects of the temperature on sound. Don't say "velocity of sound", call it "speed of sound".
How do you find the distance from a velocity time graph?
this time is basically the instant when an object has a particular velocity(instantaneous velocity). so on the graph draw a line from the particular value of the velocity and then draw a vertical line on time axis to find the time for that velocity.
