##### Relationships

frequency and period

inversely related

As frequency increases period decreases

As frequency decreases period increases

reciprocals

period x frequency = 1

power and amplitude

Directly related

when power increases so does amplitude.

power is proportional to the wave's amplitude squared.

Intensity and amplitude

Directly related

when Intensity increases so does amplitude.

Intensity is proportional to the wave's amplitude squared.

power and intensity

Directly related

proportional

when power is doubled so is intensity.

wavelength and frequency

inversely

As one increases the other decreases

As one decreases the other increases

Stiffness and speed

directly

Density and speed

inversely

Propagation speed and frequency

unrelated

Pd & period

directly proportional

Pd & frequency
