Speed = Frequency * Wave length.
Speed=Distance travelled by the object /Time taken to cover the distance.
The equation used to measure wave speed is: Wave speed = frequency x wavelength
The equation used to find the velocity of an object is v = d/t, where v is the velocity, d is the distance traveled, and t is the time taken to travel that distance.
Average speed is typically calculated by dividing the total distance traveled by the total time taken. The equation is: Average speed = total distance / total time.
If speed is constant:distance = speed x time If speed is not constant, an integral has to be used.
Please clarify what you want to calculate about the echo.
d=rt Distance=Rate (Speed) x Time This equation can be used to find Distance, Rate, and Time.
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.
Speed= distance over time. :)
The equation to calculate the speed of an object is speed = distance / time. This equation gives the rate at which an object is moving over a given distance in a specific amount of time.
The equation used to calculate average speed is distance traveled divided by the time taken to travel that distance. It is represented as: Average Speed = Total Distance / Total Time.
When an aircraft travels at the speed of sound, it is said to be travelling at Mach 1.
