Study Notes
Wave Properties
-
Wavelength (λ): The distance between two consecutive identical points on a wave, such as two crests or two troughs. Measured in meters (m). It is often represented by the Greek letter lambda (λ).
-
Amplitude (A): The maximum displacement of a point on the wave from its equilibrium position. Measured in meters (m). Represents the intensity or strength of the wave. A larger amplitude corresponds to more energy.
-
Period (T): The time taken for one complete cycle of the wave to pass a given point. Measured in seconds (s). Inversely related to frequency.
-
Frequency (f): The number of complete waves that pass a given point in one second. Measured in Hertz (Hz), where 1 Hz = 1 cycle/second. It is the inverse of the period: f = 1/T.
-
Wave Speed (v): The rate at which the wave travels through a medium. Measured in meters per second (m/s). It is related to wavelength and frequency by the equation: v = fλ. The wave speed depends on the characteristics of the medium the wave is traveling through.
