The significant feature of a Cepheid variable is that there is a relationship between two intrinsic parameters, one of which can be easily measured, while knowledge of the other parameter is required. These parameters are:

Two Velocities in a Traveling Wave? Wave motion is characterized by two velocities: the velocity with which the wave moves in the medium (e. g., air or a string) and the velocity of the medium (the air or the string itself).

Use the drop-down menus to identify the variables for the second hypothesis. Hypothesis #2: As you build circuits, you will alter resistance, which is the y variable.
