Master the Physics of Waves

Study Notes

Wave Characteristics

Waves exhibit properties such as amplitude, frequency, wavelength, speed, and phase that can be studied.
Amplitude indicates the maximum displacement from the equilibrium (rest) position.
Frequency refers to how often a wave cycles per unit of time, measured in Hertz (Hz).
Wavelength is the distance between consecutive crests or troughs in a wave.

Relationship between Wave Speed, Frequency, and Wavelength

The wave speed (v) is the product of frequency (f) and wavelength (λ): v = f × λ.
Increasing frequency results in a shorter wavelength if wave speed remains constant.
A higher wavelength correlates with a lower frequency when wave speed is unchanged.

Sound Waves

Sound waves are classified as longitudinal waves, where particles of the medium vibrate parallel to the direction of wave propagation.
They require a medium (solid, liquid, or gas) to travel and cannot propagate through a vacuum.

Applications of Wave Characteristics and Behaviors

In medicine, ultrasound uses high-frequency sound waves for imaging and therapeutic purposes.
In industry, ultrasonic cleaning employs sound waves to remove contaminants from surfaces.
Wave behaviors like reflection, refraction, and diffraction are crucial in designing optical instruments and telecommunications.

Unit of Frequency

The standard unit of frequency is Hertz (Hz), representing one cycle per second.
Frequencies can vary widely in different contexts, from low frequencies (e.g., in sound) to high frequencies (e.g., in radio waves).
