Mechanical Wave
A wave in which energy is transferred along matter, traveling at less than the speed of light.
Electromagnetic Wave
A wave in which energy is transferred independent of matter, traveling at the speed of light.
Transverse Wave
A wave in which vibrations occur at right angles to the direction of wave travel, e.g., waves on a string.
Longitudinal Wave
A wave in which vibrations occur in the same direction as wave travel, e.g., sound waves.
Frequency
The number of vibrations or wave crests that pass a point per second, measured in Hertz (Hz).
Wavelength (λ)
The distance between successive crests or troughs of a wave.
Wave Speed (v)
The distance that a wave travels per unit of time, calculated by the formula v = d/t.
Standing Wave
A wave that remains in a constant position, formed by the interference of two waves traveling in opposite directions.
Resonant Frequency
The frequency at which a system naturally vibrates, resulting in a standing wave.
Tides
Periodic rises and falls in sea level caused by the gravitational pull of the Sun and the Moon.

Wavelength (λ)
The distance between successive crests or troughs of a wave.
Wave Speed (v)
The distance that a wave travels per unit of time, calculated by the formula v = \frac{d}{t}.
Standing Wave
A wave that remains in a constant position, formed by the interference of two waves traveling in opposite directions.
Resonant Frequency
The frequency at which a system naturally vibrates, resulting in a standing wave.
Tides
Periodic rises and falls in sea level caused by the gravitational pull of the Sun and the Moon.
Fundamental Frequency
The lowest frequency at which a system vibrates, also known as the first harmonic.
Octave
An interval between two frequencies where the higher frequency is double the lower frequency.
Wave Equation
A formula that relates wave speed, frequency, and wavelength given by v = f \cdot \lambda, where f is the frequency and \lambda is the wavelength.
Particle Method
A modeling approach that represents matter as discrete particles (e.g., atoms or molecules) to analyze interactions and properties based on their spatial arrangement and movements.
Wave Method
A modeling approach that describes phenomena in terms of waves, focusing on the propagation of energy through mediums, which can include concepts like frequency, wavelength, and wave speed.
