Transverse: Displacement is perpendicular to wave direction. Longitudinal: Displacement is parallel to wave direction.

Time: $f(t) = A \cos(ωt)$ describes the wave's displacement at a given time. Position: $F(x) = A \cos(\frac{2π}{λ}x)$ describes the wave's displacement at a given position.

Frequency (f): Number of cycles per second (Hz). Angular frequency (ω): Rate of change of the wave's phase (rad/s), where ω = 2πf.

Wavelength (λ): Spatial distance of one complete wave cycle. Period (T): Temporal duration of one complete wave cycle.

General wave equation: A partial differential equation describing wave displacement in terms of space and time. Specific equations: Use sine or cosine functions to describe simple periodic waves.

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

1: Crest, 2: Trough, 3: Wavelength, 4: Amplitude

Amplitude: The vertical distance from the resting position to the crest or trough. Wavelength: The horizontal distance between two consecutive crests or troughs.

The period (T) is the time it takes for one complete cycle of the wave, measured along the time axis.

The wavelength (λ) is the distance between two consecutive identical points on the wave (e.g., crest to crest), measured along the position axis.

1. Find the period (T) from the graph. 2. Calculate the frequency using the formula: $f = \frac{1}{T}$
