Calculating Wavelength: Finding the Formula with 10cm Between Phases

[Brittykitty]

If I am given the measurement of 10cm between phases what is the wavelength? I couldn't find the formula for it in my book :S help?

Depends on the wave velocity, right?

You should be able to find the equation that relates Frequency, Wavelength and Velocity.

Or, you can just figure it out by their units:

Frequency is in 1/seconds, or Hz

Wavelength is in meters

Velocity is in meters/seconds

Since the units have to be the same on both sides of an equation, what do you think you divide by what to get what?
