Wave speed (v) is calculated as the product of frequency (f) and wavelength (λ): v = fλ.

1. Identify the amplitude (A) from the graph. 2. Determine the wavelength (λ) from the graph. 3. Substitute A and λ into the appropriate wave equation (e.g., $f(x) = A \cos(\frac{2π}{λ}x)$).

Frequency (f) is the inverse of the period (T): $f = \frac{1}{T}$

The period (T) is the inverse of the frequency (f): $T = \frac{1}{f}$

1. Identify the known variables (e.g., frequency, wavelength, amplitude). 2. Determine what you need to find (e.g., wave speed, period). 3. Choose the appropriate formula (e.g., v = fλ, T = 1/f). 4. Substitute the known values into the formula and solve.

A wave that repeats its pattern over and over again, characterized by wavelength, period, frequency, and amplitude.

The time it takes for one complete wave cycle.

The number of wave cycles that happen in one second, measured in Hertz (Hz).

The distance between two identical points on a wave (e.g., crest to crest).

The maximum displacement of the wave from its resting position.

Angular frequency (ω) is a measure of how quickly the oscillations are occurring, expressed in radians per second. It's related to frequency (f) and period (T) by the equations: ω = 2πf = 2π/T

The wavelength decreases (since v = fλ).

The wave speed changes; it depends on the properties of the medium.

The energy of the wave quadruples (energy is proportional to the square of the amplitude).

The speed of the wave increases.

The observed frequency increases.
