Just divide the wavelength by the wave period,
and you've got the wave speed.

What two factoers are used to calculate average speed?
Average speed during a period of time =(distance traveled during the time) divided by (length of the time period)
How do you solve for the speed of the wave give the formula?
One commonly used formula for waves is: speed (of the wave) = frequency x wavelength If you know any two of these pieces of information, you can calculate the third one.
A wave has a frequency of 5 Hz and a wave speed of 18 ms. What is its wavelength?
Just divide the speed by the frequency. Since SI units are used, the wavelength will be in meters.
What happens to the speed of a wave on a string when the frequency is doubled?
I believe that the speed will remain constant, and the new wavelength will be half of the original wavelength. Speed = (frequency) x (wavelength). This depends on the method used to increase the frequency. If the tension on the string is increased while maintaining the same length (like tuning up a guitar string), then the speed will increase, rather than the wavelength.
What formula is used to calculate motion?
You can use a graph to calculate speed.
What is the equation used to find the speed of a wave?
Here is an equation that relates three quantities of any wave: speed = frequency x wavelength. However, I am pretty sure that usually, you'll have to somehow measure the speed of the wave, instead of calculating it. In other words, you would measure the speed and the frequency, and then use the formula to calculate the wavelength; or measure the speed and wavelength, and use the formula to calculate the frequency.
Amplitude is the speed of the wave?
No. Aplitude is the height of the wave. Frequency and wavelength can be used to calculate the speed of the wave by multiplying them together (if the units are appropriate).
Why is wavelength all you need to know to calculate EM wave frequency in a vacuum?
Because the speed of light in a vacuum is constant(c). hence the formula, v=f.w, where v is velovity, f is frequency and w is wavelength, can be used to calculate the frequency.
Which equation should be used to calculate the speed of a wave?
That would depend what information is available. One common equation is: speed = wavelength x frequency. However, in a practical situation, it may be easier to actually measure the wavelength and (for example) the frequency, and then make deductions about the wavelength, than the other way round.

What three quantities are used to describe a wave?
Amplitude, speed, and wavelength or frequency. (Wavelength and frequency are related by the wave's speed.)
What frequency have the shortest wavelength?
For light they would be gamma rays, or waves with a frequency greater than 1 * 10^20 (10000000000000000000) Hz. And really, as a general rule, the higher the frequency the shorter the wavelength. If you want to calculate the frequency or wavelength you take the speed of light (~3.00*10^8 m/s) and divide it by either the frequency or wavelength, and your answer will be the wavelength (if you used frequency) or the frequency (if you used wavelength).
What equation is used to measure wave speed?
speed= frequency x wavelength

What are the 2 formulas given that can be used to calculate the speed of a wave?
v=fλ, where V is the speed F is e frequency and λ is the wavelength of the wave.v = c/n , where C is the speed of light and n is the refractive inde of the wave.
A wave has a frequency of 5 Hz and a wave speed of 18 ms. What is its wavelength?
Just divide the speed by the frequency. Since SI units are used, the wavelength will be in meters.
What is formula is used to calculate speed?
Distance travelled / time taken to travel the distance
